144 Version 1.2, Revision A Malfunctions and Troubleshooting88.3.1 Malfunction at the coverglass receptacleIf the Pick&Place module loses a coverglass during transport to the slide or if the Pick&Place module cannot remove a coverglass from the coverglass cartridge after 3 attempts, the user is notified of this through an error message (→ Fig. 110).1Fig. 110 Note Processing in the respective coverslip line is interrupted in order to prevent damage to the specimens. Specimens may become dried out during the interruption. LIf this message (→ Fig. 110) is displayed, the user must first check whether a coverglass has been lost during transport to the slide or whether the Pick&Place module was unable to take a coverglass from the coverglass cartridge. 1. To do this, start by opening the hood of the instrument and checking whether or not a coverglass has been lost while being transported to the slide.2. To remove the slide, press the red bar to the far right (→ Fig. 111-1) and hold it in this position.3. Make sure that the shifter (→ Fig. 111-2) does not obstruct the safe removal of the slide. Move the shifter all the way forward or back if necessary.4. Carefully remove the slide that has not yet been coverslipped from the instrument (→ Fig. 111-3) and store it safely outside the instrument. After correcting the malfunction, the slide can be coverslipped manually.
