Code Symptom
46 Toner Cartridge Not Correctly Installed
If there is a problem with one or more toner cartridges,
check the following:
1. The latch at the rear that keeps the cartridge cover locked.
2. The hook at the rear that locks the cartridge into the rotary
assembly.
3. The three color-keyed locating pins in the front of the cartridge
(that face to the rear).
4. If a good cartridge causes Code 46 to display, see
Toner Cartridge Not Installed Correctly" on page
80 Scheduled Maintenance - see Code 44.
83 Photoconductor Unit Life Warning
The photoconductor is nearing end-of-life. Do not replace the
photoconductor with another used unit for troubleshooting
purposes. If a new unit is installed and the code 83 message
remains, carefully check the density sensor ribbon cable.
84 Oil Bottle Low - see Code 42.
85 - 88 Toner Low
Remove and gently shake the cartridges. This may allow
additional usage. At this point, print quality may have degraded
and background will become more pronounced (end-of-life).
If this code applies to one cartridge which is known to be new,
check the two windows on the cartridge for damage or debris.
If the machine reports all cartridges low, check the toner low
detect PCT (Beam) and toner low detect PCB (Receive). Refer to
the Block Wiring Diagram Sheet.
