Appendix B
Periodic Replacement
Parts
Some of the component parts of the printer naturally deteriorate over
time. Periodic replacement of these parts will ensure the highest quality
output from your printer.
The following table gives suggested intervals for replacing these parts.
Because the life span of periodic replacement parts depends on how the
part was used, it may have to be replaced earlier than the time indicated
below. If you use a periodic replacement part beyond its specified life
span, printing quality may be reduced and errors or paper jams may occur.
A service engineer should replace these parts. Contact your dealer or
authorized Tally service representative.
Note
:
After high-volume printing conditions (approximately 100,000 to
600,000 pages), the control panel may begin to display messages indicating
that certain printer parts are worn and need to be replaced (refer to
“Appendix D Control Panel Messages” on page 141 for more information).
These parts should only be replaced by a qualified service technician or a Tally
service engineer.
