Subject: Mannesmann Tally MT645, MT660, MT661, MT690 & MT691 End of Support – CRITICAL UPDATE
The End of Support notice on June 30, 2011 for the Mannesmann Tally MT645, MT660, MT661, MT690 and MT691 Line Matrix
Printer models signaled critical high-usage spare parts from the manufacturer were severely impacted. The ability to supply parts
and perform repairs would be extremely limited/discontinued and that Printronix Technical Support will no longer be provided.
These printers were manufactured between 1992 and 1998 with planned new spare parts available for 5 years past the last
manufacture date. Today, the inability to source components and manufacture parts that meet our specifications has resulted in
high failure rates as reported by our customers. This is a critical warning and reminder of the End of Support status.
High usage parts that are in critical short include:
Hammer Bank (print engine) & HammerSprings (Frets)
Power Supply
Blower Assembly
Logic Board & Power Distribution Boards
We recommend an upgrade to the TG6800 Printer, a seamless and improved offering with the following benefits:
o Reduced Cost of Ownership, an estimated 25% cost per page savings over your current model
o Superior up-time reliability, performance, print quality and lowest cost per page printing
o Go to: www.tallygenicom.com or www.printronix.com to learn more about your upgrade options.
Obtain a Genuine Printronix on-site maintenance plan from an authorized P.A.R.T
Service Provider that can be specifically designed to cover you temporarily while you
evaluate your upgrade options. This is the only way to ensure you are receiving factory
guaranteed parts and service provided by highly trained and authorized technicians.
o Don’t trust third party service providers who often utilize used parts, resulting
in poor print quality, bad barcodes, paper jams and increased print failures; all
of which negatively impact productivity.
o To ensure you are purchasing your Printronix service contract from a P.A.R.T.
Provider, look for the badge to the right.
To request your free print/upgrade analysis and discuss transitional maintenance coverage, purchase and finance options or to

Critical High Risk Parts:
Hammer Bank/HammerSpring (Fret) Issues
• Concern: Hammer Bank Calibration/Hammer Spring (Fret) tip wear over time.
• Encountered Problem: Poor print quality and unreadable barcodes due to improper dot
formation. Light and dark areas of print, premature and reduced ribbon life.
Note: Calibrating the retract setting of each hammerspring is a highly precise process. Only the
Printronix factory can warrant this process which requires specials tools, jigs, training and calibration
equipment. Relying on used, non-factory sources result in problems due to worn carbide tips, improper
retract settings, resulting in needless expensive repairs and additional problems.
Power Supply
• Concern: Power supply failure exhibits erratic printing/additional component damage.
• Encountered Problem: Power supply failure can exhibit poor print quality, sub-system damage
and is a potential safety hazard. The shendingan power supplies are no longer manufactured.
Blower Assembly
• Concern: Decreased print thru-put/diminished print quality/additional component failure.
• Encountered Problem: Print thru-put diminished due to thermal throttling of the hammer bank.
Hammer bank coil overheating requiring hammer bank replacement and the associated problems.
No form/fit 48 volt blower equivalents are manufactured any longer.
Logic Board & Power Distribution Board Assemblies
• Concern: Poor print quality/increased LCD Errors/erratic sub-system behavior.
• Encountered Problem: Data not being processed properly resulting in poor print quality and
incorrect print. Sub-system monitoring and control failure for the paper, ribbon and Hammer
Bank thermal monitoring resulting in poor print quality, abnormal paper/ribbon movement
and intermittent error messages resulting in print stoppage and downtime.
Note: Printronix continues to support printer ribbons for the products mentioned above.
