Testing Belt Tension
Verify that belts are properly tensioned by using the System Test (available through the Touchscreen or Toolbox).
Before running the System Test, make sure that the Printer is powered up, all Printer systems are connected and
functioning, and the paperpath is clear of obstructions. Once you run a System Test, use the result to determine if
the belt adjustment for that system is within parameters or if loosening or tightening the belt(s) is required.
IMPORTANT!
Failure to properly tension belts can cause poor Printer
performance and premature component failure.
NOTE: These tests should only be performed by authorized service personnel.
System Test allows testing individual or all Printer
systems to check that they are operating within
specifications. It also allows service people to
check the Printer after servicing or replacing parts,
particularly belts.
NOTE: Some component/belt replacements may
require adjusting/checking multiple Printer
systems/belts each time an adjustment, servicing
or replacement is performed.

1. System Test can be accessed from the
Touchscreen or Toolbox:
