Atc Sensor (K); New Toner Cartridge (K) - Xerox DocuColor 1632 Service Manual

9-383 ATC Sensor (K)

The ATC Sensor (K) detects an insufficient amount of developer material
Initial Actions
ï Check that Toner/Developer is present.
ï Check the ATC Sensor (K) for contamination. Ensure that the sensor is seated correctly.
Procedure
NOTE: To clear this fault, enter dC131 and set the value of NVM location 752-110 to 0.
Record the value in NVM location 752-324, then set the value to 1. Perform
measurement has completed, restore the value. The ATC Sensor (K) Fail judgement is OK.
Y N
Check the connector P/J132 If the check is OK, replace the ATC Sensor (K) (PL 6.2). If
the problem continues, replace the MCU PWB (PL 13.1).
After checking that no failures are detected during normal operation, go to call close out.

9-390 New Toner Cartridge (K)

The New Cartridge Detect Switch (K) was not engaged to reset the Accumulative Dispense
time NVM value to 0 when a new cartridge was installed.
Initial Actions
ï Re-install the Toner Cartridge ensuring that the Dispense Motor and the Toner Cartridge
is engaged.
ï Check that the New/Old Detection Switch (metal part) at the rear of the Toner Cartridge is
raised. If the New/Old Detection Switch is not raised, lift it up, then set NVM location 752-
686 (Accumulative Dispense Time Value K) to 0.
ADJ 9.3. After the
ï Check that the Dispense Motor is operating; check
Procedure
Disconnect P/J405 from the MCU PWB. The fault has cleared.
Y N
Replace the MCU PWB. (PL 13.1)
Remove the Toner Cartridge K and check the Dispense Motor Assembly for ware or damage.
Disconnect FS186/187 at both edges of the New Cartridge Detect Switch (K).
Check continuity at both edges of the New Cartridge Detect Switch (K). There is continuity
when the Switch is not engaged.
Y N
Check the wire between the connector j405-A18 and the New Cartridge Detect Switch (K)
FS187 for a short circuit to the frame.
Replace the New Cartridge Detect Switch (K). (PL 16.1)
