Printronix P7000 User Manual page 313

To clean the interior of the printer perform the following steps.
1. Power off the printer and unplug the printer power cord.
2. Open the printer cover.
3. Fully raise the platen lever.
4. Unload the paper.
5. Unlatch the ribbon and ribbon spool and carefully lift them off
the hubs.
6. Lift the ribbon out of the ribbon path.
7. Brush the paper dust and ribbon lint off the tractors, shuttle
cover assembly, base casting, and ribbon guides with a soft-
bristled, non-metallic brush (such as a toothbrush). Vacuum up
the residue.
CAUTION
Vacuum carefully around the hammer bank and surrounding
area to avoid damage. To avoid corrosion damage, use only
alcohol when cleaning the printer mechanical elements.
Solutions used to clean mechanical elements must contain no
water.
8. Wipe the splined shaft with a soft cloth.
9. Check the ribbon mask and hammer bank cover for bits of torn
paper or ribbon lint.
10. Remove dust and ink from the platen using a soft cloth lightly
moistened with anhydrous alcohol. (The platen is the thick
silver bar behind the hammer bank cover that rotates when the
platen lever is rotated.) Clean the ribbon guides.
CAUTION
When cleaning the platen, be very careful not to get any
alcohol in the hammer bank, because alcohol will cause
severe damage to the hammer bank. Only a trained service
technician should clean the shuttle assembly.
