1. INTRODUCTION
This manual contains information for the programming and operation of the High Speed
Printer Subsystem for the UNIVAC 1108 Multi-Processor System.
It is assumed that both the programmer and operator have sufficient background information
on the Central Processor and Main Storage of the UNIVAC 1108 Multi-Processor System, and
need only to be instructed in the use of the High Speed Printer Subsystem. Therefore, material already covered in the "UNIVAC 1108 Multi-Processor System Processor and Storage
Reference Manual," UP-4053, will not be duplicated here.
This manual is divided into three basic sections:
•
High Speed Printer Subsystem Description
This section will acquaint the reader with the characteristics of the High Speed Printer
Subsystem.
•
Programming
This section supplies the user with the information required for programming for the High
Speed Printer Subsystem.
•
Operation
This section contains the information necessary for the operation of the High Speed
Printer Subsystem.
Referencing the programming section within this manual on a regular basis is unnecessary
when appropriate software is available as an interface to the High Speed Printer Subsystem.

2. SUBSYSTEM DESCRIPTION
2.1. GENERAL
The High Speed Printer Subsystem provides the UNIVAC 11 08 Multi-Processor System
with an output printing unit which operates at a rate up to 922 lines per minute, printing single or multiple copies of data. Each line of output data may contain up to 132
printed characters. Printing operations occur on a request-acknowledge basis allowing
the processor to attend to other processing functions while the printer is actually
printing data.
The High Speed Printer (Type 0755 or 0751 *) and the High Speed Printer Control Unit
(Type 7299-03) comprise the printer subsystem for single printer applications. For the
optional dual printer applications, the subsystem includes two High Speed Printers and
both the Control Unit, Type 7299-03, and the Auxiliary Control Unit, Type 7299-04.
Each control unit may be connected to either a normal or compatible I/O channel of
the processor, or its logical equivalent (the Input/Output Controller or a Multiple Processor Adapter). Output information is routed by the processor through the Printer Control Unit to the Printer. The Printer Control Unit contains a 132-character core buffer
for accumulating a full line of information before printing.
The printer contains 63 printable characters - the 26 letters of the alphabet, the ten
numerals, and 27 special characters. Different symbols may be factory-supplied upon
order.
The capabilities and salient features of the individual units of the Printer Subsystem
are presented in Tables 2-1 and 2-2.
• This manual deals primarily with the High Speed Printer, Type 0755. For subsystems equipped with
the Type 0751 Printer, refer to Appendix A.

Subsystem components, described in the following paragraphs, include the High Speed
Printer and the High Speed Printer Control Unit.
2.3.1. High Speed Printer, Type 0755
The High Speed Printer, Type 0755 (see Figure 2-2), is an "on-the-fly" impact printer.
Its operation is based on a printer mechanism which consists of the following main parts:
•
rotating type drum,
•
printing actuators and hammers,
•
ribbon-transport mechanism,
•
paper-transport mechanism.

Printer Mechanism
The type drum is a cylinder with raised printing surfaces around its circumference.
The individual characters of adjacent positions are staggered and form a checkerboard pattern on the type drum to prevent smudging or partial printing of adjacent
characters. Table 2-4 shows the printed characters and their corresponding octal
codes. As the type drum revolves, timing circuits control the action of each printing
actuator and hammer. When the proper character is opposite the hammer, the hammer
strikes the paper and pinches the ribbon between the paper and the type drum to
print a character. The hammer plate and the paper transport are rigidly mounted to
the frame of the printer. The type drum and the ribbon transport are in a movable
carriage. The carriage moves in toward the hammer plate for printing, and out
from the printing position for servicing. The space between the type drum and the
hammers is adjustable, so that either single-thickness paper or multiple copy forms
may be used.
The ribbon-transport mechanism moves the ribbon in front of the type drum. When all
but a short length of ribbon has been wound off the supply mandrel, the ribbon-transport mechanism automatically reverses and winds the ribbon in the other direction.
The ribbon transport starts and stops the ribbon each time the paper is moved by the
paper-transport mechanism.

Table 2-4. Processor Code/Printer Symbol Assignment
The paper-transport mechanism feeds paper, a line at a time, under subsystem control.
A maximum number of 63 lines can be fed for each print function. The mechanism consists of two sets of pin-feed tractors, adjustable for form width from 4 through 22
inches and for margin placement. The lower set of tractors draws pap,er from the
supply container and passes it to the upper tractor. The tension of the paper between
the upper and lower tractors is adjustable and does not vary with the weight of the
paper stock. Printed pages pass from the upper tractors over guides and out the rear
of the printer, where they are collected on a shelf. Controls on the printer control
panels provide adjustment for proper printing placement, paper tension, and margin
settings.

2.3.2. High Speed Printer Control Unit
The control unit (see Figure 2-4) governs all the operations of the High Speed Printer
Subsystem. Its principal functions are:
•
to receive function words from the processor and translate them into control signals
for the printer,
•
to synchronize the flow of data between the processor and the printer,
•
to accumulate a line of print in its buffer memory from the data transmitted by the
processor,
•
to interpret signals, both normal and abnormal, from the printer and to notify the
processor of printer and control unit conditions.
Figure 2-4. High Speed Printer Control Unit
2.3.2.1. Buffer Memory
The buffer memory used in the control unit is a random access, ferrite-core memory
with a usable storage capacity of 132 seven-bit characterso
Information is transferred between the processor and the Printer Subsystem in the
form of 36-bit data words. Each such word is disassembled into six-bit characters
and stored in the buffer memory until a full line of print (132 characters) is accumulated in the buffer memory. When a stop code or a Terminate function is received by
the control unit, the number of data words necessary to fill the buffer memory is
reduced. For example, the control unit automatically fills the remaining memory
positions with a nonprintable code, on the receipt of a stop code.

3. PROGRAMMING
3.1. SUBSYSTEM/PROCESSOR INTERFACE
Communications between the processor and the Printer Subsystem are over a pre-assigned
input/output channel(s). Each channel contains 72 data lines (36 input and 36 output) and
6 control lines. The data lines provide for the parallel transfer of the basic UNIVAC 1108
processor word and the control lines provide various control signals that direct the communication between the processor and the control unites).
3.1.1. Communication Modes
Each channel is capable of operating in three different communication modes: function,
output, or input. The function mode is the means by which the processor establishes
communications with the Printer Subsystem. During this mode of transmission, the
processor sends a function word to direct the control unit to perform the desired
operation. The output mode is employed when data is transferred to the processor
and the input mode is used to transmit status information to the processor.
3.1.2. Control Signals
Various control signals are provided to control and insure the orderly flow of information between the processor and the Printer Subsystem. These signals do not transmit
data but are used to command and to identify the transfer of information words at the
proper time and in the proper sequence. The control signals travel over the control
lines of the channel(s) associated with the subsystem.
A listing of these signals follows:
C:
•
Output Request (OR) - indicates to the processor that the control unit will accept
a function word or a data word that is to be printed.
•
External Function (EF) - indicates to the control unit that the processor has placed
a function word on the output lines.
•
Output Acknowledge (OA) - indicates to the control unit that a word of data has
been placed on the output lines.
•
External Interrupt (EI) - indicates to the processor that the control unit has status
information on the input lines.
•
Input Acknowledge (I A) - indicates to the control unit that the processor has
accepted the status word.
•
Master Clear (MC) - clears the control unit.

3.1.3. Sequence of Operation
C'
The Printer Subsystem gives the program the capability of spacing paper the desired
number of lines and printing one line or multiple lines of data. The Printer Control
Unit conforms to the following sequences during its operation:
•
Function Handling - to receive, decode, and verify the legality of the function
words that are transmitted by the processor.
•
Paper Spacing - to control the paper spacing operation of the printer as specified
by the function word.
•
Data Handling - to receive and disassemble the data words into 6-bit characters
for storage in the buffer memory until one full line of data is received from the
processor.
•
Printing - to initiate printing when the buffer memory has been fully loaded and
the paper spacing operation is completed.
3.2. WORD FORMAT
The Printer Control Unit controls the operation of the Printer Subsystem through the
following three types of 36-bit words: function words, data words, and status words.
Each word type has its own format and each word is accompanied by a signal along
one of the control lines to distinguish between the three types of words. Two of these
(function word and data word) are processor-supplied words; the third (status word)
originates in the subsystem.
3.2.1. Function Words
The function word instructs the control unit to initiate a subsystem operation. The
six high order bits (35 thru 30) specify the operation to be performed, while bit
positions 23 thru 18 specify the line spacing count (0 to 63 lines inclusive) for print
functions only. The format of the function word is shown in Figure 3-1, as follows:

The function repertoire of the High Speed Printer Subsystem consists of four functions
as follows:
•
Print with Interrupt
•
Print without Interrupt
•
Terminate with Interrupt
•
Terminate without Interrupt
Each of these functions is described in detail in the following paragraphs.
3.2.1.1. Print With Interrupt
Function Code:
128
The Print with Interrupt function instructs the subsystem to space paper as defined
by the line spacing count of the function word and to print a single line of data.
Printing is initiated after both the line spacing and the data transfer are complete.
Twenty-two data words are required to complete the data transfer for a full line of
print (132 characters). The data transfer for a partial line of print is complete when
either a Terminate function is received following the transfer of one or more data
words or a stop code (a character code of all 1 bits) is detected within a data word,
providing the 62 CHAR/63 CHAR switch on the Maintenance Panel is in the 62
CHAR (up) position. Upon successful completion of printing the line, a status word
containing the Normal Completion status code (40) is generated by the control unit
and the External Interrupt signal is turned on.
The control unit does not turn on the Output Request signal following the receipt
of the 22nd data word for the line, or following receipt of a data word containing
a stop code (when conditioned for 62 CHAR operation) until after the processor
has either acknowledged receipt of a Norm al Completion status code or sent a Terminate without Interrupt function to the subsystem.
3.2.1.2. Print Without Interrupt
Function Code: 028
The Print without Interrupt function instructs the subsystem to space paper as
defined by the line spacing count of the function word and to print ithout interruption, any number of equally spaced lines. Printing is initiated after both the
paper spacing and data transfer are complete.
Following receipt of the 22nd data word for a line, or the receipt of a data word
containing a stop code (when conditioned for a 62 CHAR operation), the control
unit does not turn on the Output Request signal until after the line has been printed
without detection of an error, or after a Terminate function has been received and the
control unit is ready to accept the next print function.
UNIVAC 1108
UP-7s09

SECTION. "

PAGE.
Upon completion of the first and each successive line of printing, the control unit
retains the original function word with the same line spacing count and waits for
the data for the next line of print. The Print without Interrupt operation can be ended
by one of the following conditions:
•
Fault or abnormal condition
•
Terminate function
c
If a fault or abnormal condition is detected, the operation is concluded when the
External Interrupt signal is turned on and a status code representing the fault or
abnormal condition is generated by the control unit. Otherwise, the Print without
Interrupt must be concluded by a Terminate function when the data in the output
buffer has been exhausted. The processor can anticipate the completion of the last
line of printing by selecting the monitor interrupt feature when setting up the output
data buffer for a Print without Iilterrupt function. When the control unit requests
another data word after receiving the last data word in the output buffer, the Output
Monitor Interrupt will occur. The program should then terminate the Print without
Interrupt function. It is recommended that the Terminate with Interrupt function be
used so the program will be informed when the Print without Interrupt function has
been completed and the subsystem is ready to accept another print function.
3.2.1.3. Terminate With Interrupt
Function Code: 338
The Terminate with Interrupt function instructs the subsystem to conclude the function
currently being performed by the subsystem and to establish readiness for another
function. It may be issued by the processor at any time and brings about an orderly
stop without the loss of data. The Terminate with Interrupt function will normally
result in the External Interrupt signal being turned on and the transmission of a
status word containing the Normal Completion status code (40).
C
If a Terminate with Interrupt function is received following one or more data words
for either print function, the response to the Terminate function will occur after the
words are printed. If an Interlock condition is detected, it will be reported immediately
and replace the Normal Completion status code. Likewise, the Out of Forms condition
will take precedence over the Normal Completion status code.
In the event that the Terminate with Interrupt function is received before a word of
data is received by the control unit, the termination will take place as follows:
• If terminated within 6.5 microseconds of the receipt of the current print function,
paper spacing is inhibited and the External Interrupt signal is turned on and the
Normal Completion status (or Interlock, if appropriate) code is generated within .5 microseconds .
•
If terminated 6.5 microseconds or more after the receipt of the current print function, the External Interrupt signal is turned on and the Normal Completion (or
either Interlock or Out of Forms, if appropriate) status code is generated after
paper spacing is completed.

3.2.1.4. Terminate Without Interrupt
Function Code: 238
The Terminate without Interrupt function concludes the previous print operation.
Depending upon conditions, termination takes place as follows:
•
If terminated within 6.5 microseconds of the receipt of a print function, paper
spacing is inhibited and the OR signal is normally turned on within 1.8 microseconds to notify the processor that the'control unit is ready to accept the next
function word.
•
If terminated 6.5 microseconds or more after the receipt of the current print
function, the OR signal is normally turned on again after paper spacing is completed.
•
If one or more data words are received by the control unit, termination becomes
effective after printing is completed and the OR signal is normally turned on to
notify the processor that the control unit is ready to accept the next function
word.
If an Interlock or Out of Forms condition is detected during the execution of either
print function, the condition is reported to the processor. If a Terminate without
Interrupt is received before the processor acknowledges the Interlock or Out of
Forms condition, the control unit's response to the Terminate without Interrupt
function is to report the condition rather than to turn on the Output Request signal.
(
The primary use of the Terminate without Interrupt function is to clear the control
unit following receipt of a status word containing a status code other than the
Norm al Completion status code.
3.2.2. Status Word
The status word is generated by the control unit to indicate the detection and nature
of special conditions in the subsystem. The status word is transferred to the processor
over the 36 input data lines, accompanied by a signal on the external interrupt line to
inform the processor that a status word is available. The status code occupies the
six most significant bit positions of the status word with the two least significant
bits of the status code always containing 0 bits. The remainder of the status word
also contains 0 bits. The format of the status word is as follows:

The Printer Subsystem can generate any of four status codes reflecting the detection
of the following conditions:
C
- Normal Completions
- Out of Forms
- In valid Function
- Interlock Fault
Each of these conditions and the status codes associated with them are described in
the following sections.
3.2.2.1. Normal Completion
Status Code: 408
The Normal Completion status code is possible only as a response to Print with
Interrupt (12) function and a Terminate with Interrupt (33) function and indicates
to the processor the successful completion of these functions. When a Normal
Completion status word is acknowledged by the processor, the control unit turns
on the Output Request signal and is ready to accept and initiate the next print
function. If a data word rather than a function word is received in response to this
Output Request signal, the control unit ignores the data word and does not request
another data word but remains ready to accept and initiate a print function.
If a fault or abnormal condition occurs in the interval between receipt of a Terminate
with Interrupt and the actual conclusion of a print operation, the fault condition takes
precedence and_ the appropriate status code is presented to the processor.
3.2.2.2. Out of Forms
Status Code: 448
The Out of Forms status code is generated by the control unit when the printer
determines there is insufficient paper to print a maximum of 15 single-spaced lines
at 6 lines per inch or. 20 single-spaced lines at 8 lines per inch (approximately 2.5
inches of paper). Th~ condition is detected only when there is a transition from
paper to no paper during the paper spacing sequence for the printing of a line. The
status code is made available to the processor upon completion of printing that
line. When the processor acknowledge,s receipt of an Out of Forms status word, the
control unit does not turn on the Output Request signal. Before the control unit can
accept a new print function word, a Terminate function (23 or 33) must be issued.

3.2.2.3. Invalid Function
Status Code: 508
The Invalid Function status code informs the processor that either the function
word received by the control unit specifies a function code not included in the
subsystem repertoire, or a data word was received in response to an Output Request
signal which was turned on following a Terminate without Interrupt function, or a
print function was received by the control unit when it was not ready for a print
operation. Anyone of these conditions causes the current function to be aborted
and the External Interrupt and the Invalid Function status code to be presented
to the processor immediately. When the processor acknowledges receipt of an Invalid
Function status word, the control unit does not turn on the Output Request signal.
Before the control unit can accept a new print function word, a Terminate function
(23 or 33) must be issued.
3.2.2.4. Interlock Fault
Status Code: 748
The Interlock Fault status code informs the processor that one of the following
abnormal conditions has occurred in the printer:
(-
•
Printer Power Fault
•
Paper Runaway (paper feed greater than 22 inches)
•
Ribbon Out
•
Cabinet Interlocks Open
•
Overheat
•
Carriage Out
Manual intervention is required before further operations on the printer are attempted.
When the control unit acknowledges receipt of an Interlock Fault status word, the
control unit does not turn on the Output Request signal. Before the control unit can
accept a new print function word, a Terminate function (23 or 33) must be issued.
3.2.3. Data Word
The data word contains the information to be printed. After the function word is received
and acted upon, data words are transferred from the processor to the subsystem. The
data word is a 36-bit processor word. Characters within a series of data words are
printed consecutively from left to right starting with the most significant character
and ending with the least significant character.

3.3. TIMING
The variables which affect timing on the High Speed Printer Subsystem are described
below.
o
3.3.1. General Characteristics
The increments of time which determine the printing speed upon receipt of a Print
Function by the control unit are as follows:
• Liile Spacing Sequence
•
Buffer memory loading sequence
•
Compare/print sequence
•
Processor/program response time
3.3.1.1. Line Spacing Sequence
The control unit initiates the line spacing sequence when either form of print
function is received. For the second or subsequent lines to be printed for a Print
without Interrupt function, the sequence is initiated when the first word of data is
received.
A print function with no line spacing encounters a 19-millisecond delay before the
line spacing sequence is considered complete. For a print function with line
spacing, the time is dependent on the spacing count and the setting of the 6 LI/
8 LI (6-LINES/8-LINES) switch on the printer. Table 3-1 lists the time required
for completion of the line spacing sequence for various line spacing parameters.

SECTION:
PAGE:
3.3.1.2. Buffer Memory Loading Sequence
This sequence is performed as follows:
(1) The control unit turns on an Output Request signal asking for a data word.
(2) The processor responds by sending a data word and an Output Acknowledge
signal.
(3) The control unit turns off the Output Request signal and stores each 6-bit
character of the output data word in its buffer memory. For each character,
an additional bit in the 7th level is stored in the buffer memory to indicate
whether or not the character is to be printed. The 7th level will contain a
1 bit for printable characters and a 0 bit for all nonprintable characters.
(4) The control unit cycles through these steps until it has stored the data from
22 words in its buffer memory or until it receives a data word containing a
stop code.
The buffer memory loading sequence is initiated following receipt of a print
function word when the Output Request signal asking for the first data word is
turned on (4 microseconds after the function is received).
If a stop code is detected in a character of any data word, the buffer memory
position corresponding to that character and all subsequen t buffer memory
positions are padded out and include a 0 bit in the 7th level to indicate
that a character is not to be printed for those positions.
For the second and each subsequent line to be printed for a Print without Interrupt
function, the buffer memory loading sequence is normally initiated one microsecond
after completion of the compare/print sequence for the previous line. However, if
the compare/print sequence for the first line is completed within 60 milliseconds
of the receipt of the Print without Interrupt function, or the compare/print sequence
for the second or a subsequent line is completed within 60 milliseconds of receipt
of the first data word for that line, then initiation of the buffer memory loading
sequence for the next line is delayed until the 60-millisecond delay timer has
expired. It should be noted that if a Terminate function is received in lieu of the
first data word for the second or a subsequent line while executing a Print without
Interrupt function, the buffer memory loading sequence for that line is aborted and
the Print without Interrupt function is considered complete.
The buffer memory loading sequence is considered complete when:
(1) data from 22 words have been stored in the buffer memory, or
(2) the control unit finishes loading the buffer memory by padding it with nonp rin ta ble co des after:

Interrupt function or for the first line to be printed for a Print without
Interrupt function, or
•
receiving a Terminate function in lieu of the second or a subsequent data
word for the second or a subsequent line for a Print without Interrupt function.
o
The time required for completion of the buffer memory loading sequence is dependent
on how soon the processor responds to each request for an output data word. The
minimum time required for completion is about 600 microseconds. The buffer memory
loading sequence is normally overlapped by the line spacing sequence.
3.3.1.3. Compare/Print Sequence
The printing of a line is started when both the line spacing and loading sequences
are completed. The compare/print sequence is comprised of the following factors:
., synchronization of the control unit with the print drum.
•
comparison of each of the 132 codes stored in the buffer memory with each code
read from the code wheel of the print drum .
•
determining whether or not all printable codes stored in the buffer memory have
been printed.
The print drum and code wheel tum at 922 revolutions per minute (65 milliseconds
per revolution). The code wheel has the binary codes for 63 printable symbols
equally spaced around its periphery with an interval of 1,033 microseconds between
consecutive codes. Table 3-2 shows the sequence of the 63 printable symbols which
appear on the standard print drum with the octal codes for each symbol.
Each time a code is read from the code wheel, the buffer memory is scanned. A
comparison is made between the code read and the contents of each of the 132
positions in the buffer memory which contain a 1 bit in the 7th level. For each
position in which the compare equal is detected, the corresponding print actuator
is fired and the position in the buffer memory is charged to a nonprintable code
(7 level = 0 bit). During each scan a check is made to determine whether or not
any printable codes (7th level = 1 bit) were read from the buffer memory. If no
printable characters are recognized, the compare/print sequence for the line is
considered complete.
When the compare/print sequence is complete for a Print with Interrupt function,
the status word is generated and the External Interrupt signal will be turned on
within one microsecond after completion or 60 milliseconds after receipt of the
print function, whichever is latest. If the status code is Normal Completion, the
Output Request signal is turned on and the control unit is conditioned to receive
the next function within one microsecond of the time the External Interrupt signal
is acknowledged.

3.3.1.4. Processor/Program Response Time
The processor/program response time is the interval from turn on of the External
Interupt signal until the time of receipt of the next print function by the control
unit. It is significant in determining maximum printing rates.
The processor/program response time can be affected in varying degrees by any
of the following:
•
The delay encountered until the processor's priority circuitry permits recogni.tion
of the External Interrupt signal.
•
Delays encountered while processing other higher priority interrupts or I/O
operations.
•
Analysis of the status word received from the control unit.
•
Selection of the next print function and sending it to the control unit.
3.3.1.5. Printing Speed
The variables which determine the time to print a series of lines are:
•
the line spacing sequence time
•
the buffer memory loading sequence time
•
the compare/print sequence time
•
the processor/program response time.
The following example discusses these variables and calculates the number of
sequential sym boIs which can be printed at 922 lines per minute:
Assume that the Print with Interrupt (128) function specifying single
line spacing is used, that the line spacing sequence overlaps the
buffer memory loading sequence, and that the processor/program
response time is 300 microseconds.
To print at 922 lines per minute, a line must be printed for each
revolution of the drum, (every 65.076 milliseconds). Subtracting 19
milliseconds for line spacing time; 300 microseconds for the
processor/program response time, and 1,033 microseconds (the time
for completion of the compare/print sequence); leaves 44.743 milliseconds for all but the final scan cycle of the compare/print sequence.
Dividing this value by the 1,033 microseconds, the time required for
each scan cycle, the result is slightly more than 43.
Printing can proceed at 922 lines per minute using Print with Interrupt functions
when the characters to be printed on each line fall within a consecutive range of
43 out of the 63 characters on the print drum.

4.2.2.2. Control Unit's Maintenance Panel
The Control Unit's Maintenance Panel, shown in Figure 4-5, is primarily of
significance to the Univac Field Engineer, permitting him to control and observe
certain subsystem operations. The panel is located behing the back cover of
the control unit.
Two toggle switches (62 CHAR/63 CHAR and PTR) and two pushbutton switches
(POWER CONTROL - OFF and ON) located at the bottom right side of this
panel may be of significance to the operator. The functions of the switches
are as follows:
62 CHAR/63 CHAR: In the 62 CHAR position, the 05 8 and 778 codes are nonprintable. The 778 code is defined as a stop code which causes all characters
which follow it to be nonprintable. The 62 CHAR position is normal. The 63
CHAR positio~ permits operating with the 058 code as the only nonprintable
code.
POWER PTR/OFF switch: This switch should always be in OFF (down)
position.
POWER CONTROL/OFF and ON: These switches control the AC power applied
to the control cabinet.

4.3. SUBSYSTEM OPERATION
The following paragraphs describe the turn-on, turn-off and paper loading procedures
for the subsystem.
c
4.3.1. Turn-On Procedure
Before initiating the procedure for turning on the subsystem, the condition of the
lSI (local/remote) switch located on the printer and that of the PTR switch on
the control unit must be determined. It is recommended that the conditions of these
switches satisfy local turn-on and subsystem power be turned on at each unit.
For local turn-on, the recommended procedure is as follows:
4.3.1.1. On The Control Unit
Before turning on the control unit make certain that all cabinet panels are in
place, all interlocks are closed and that maintenance work is not being done on
the unit.
(1) If conditions are normal, ensure that the PTR switch, located on the Maintenance Panel, is in the OFF (down) position.
(2) Place the 62 CHAR/63 CHAR switch, located on the Maintenance Panel,
in the desired position.
(3) Depress the POWER CONTROL ON switch. The OFF SWITCH indicator
located on the Operator Panel will light green.
4.3.1.2. On The Printer
Before attempting to turn power onto the printer, make certain that all cabinet
panels are in place and closed, the interlocks are closed, and maintenance is
not being done on the unit.
(1)
If prepower conditions are normal at the printer, only the POWER FAULT
indication is lit on the Diagnostic Panel.
(2)
Depress the AC/DC switch/indicator on the Left-hand Control Panel. If
the AC indicator does not light immediately, check the circuit breaker
panel on the rear of the printer.
(3) If a circuit breaker opens, its associated button on the circuit breaker
panel pops out. Depress the circuit breaker button to reset the circuit
breaker.
(4)
If the DC portion of the AC/DC switch/indicator does not light, remove
the rear paper guide, the paper-storage tray, and the guide adjusting bar
from the rear of the printer. Open the access panel and locate the DC
circuit breaker. The lCBl circuit breaker .switch should be in the up
position as shown in Figure 4-3.

CAUTION
If any circuit breaker cannot be reset or if, when reset,
the fault persists, call a Univac Field Engineer.
(5) When the circuit breakers are all reset, close all the cabinet panels and again
depress the AC/DC switch.
(6) If there are no further faults, the AC and DC indicators light and after a 45second delay, the READY indicator lights automatically. If the FORMS OUT
fault indicator is lit, a new paper form must be loaded before operation.
4.3.2. Turn-Off Procedure
The procedure for turning off the subsystem involves taking the necessary precautions
to insure that no print operations are in progress and then remove power from the
units in the following sequence:
- Printer: Depress AC/DC switch, located on Left-hand Control Panel, indicator
extin guishes.
- Control Unit:
Depress OFF switch, located on Operator Panel,
lights red.

4.3.3. Paper Loading Procedure
(1) Depress the OFF LINE switch/indicator (indicator lights) so that the FORM
ADV ANCE switch can be activated.
(2) Depress the CARRIAGE OUT rocker pushbutton. Raise the transparent top
cover and lift the retaining clamps on both sides of the form.
(3) Lift the old paper off the sprockets and slide it through to the rear of the
printer.
(4) If forms of the same width are to be loaded and the print line is not shifted
right or left, ignore steps 5, 6, 8, 9, and 10 for releasing and repositioning
the tractor locks. If forms of different widths are to be loaded, release the
top tractor locks on the Type 0755 Printer and/or the top and bottom tractor
locks on the Type 0751 Printer.
(5) Depress the rocker pushbutton labeled BOTH on the Right-hand Control Panel
away from the BOTH position to uncouple the tractor control knobs.
(6) Position the tractor locks by means of the left and right tractor knobs on the
Right-hand Control Panel so that they are spaced approximately the width of the
form to be loaded.
