Replace Trailing Cables
Before replacing the trailing cables from the printer always remove power
from the printer.
The trailing cables (2 total) are rated for approximately 2000 hours of operational usage.
Many factors including, but not limited to, hours/day used, cleanliness of the trailing cable
surfaces and general ambient environment make it impossible to calculate the average
time that the trailing cables will last. If the trailing cables are cleaned weekly the life of
the cables should effectively double.
If not replaced, the wear on the trailing cable flexible printed circuits can result in erratic
carriage motion and/or carriage axis failures, vertical white bands (jumps) in printed
output, vertical color band jumps, and unrecognized cartridge error messages. Cables
should always be replaced in sets (never replace one cable only).
To replace the trailing cables, follow the procedures for Trailing Cable Replacement
found in Chapter 5.
