Atc Sensor (K) - Xerox DocuColor 2240 Service Manual

9-383 ATC Sensor (K)

The ATC Sensor (K) detects an insufficient amount of developer material
Initial Actions
• Check that Toner/Developer is present.
• 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 752-112 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
Refer to Figure 1 and check connector P/J132. If the check is OK, replace the ATC Sen-
sor (K) (PL 6.2). If the problem continues, replace the MCU PWB
After checking that no failures are detected during normal operation, go to call close out.

Initial issue
DC 3535/2240/1632
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
• Re-install the Toner Cartridge ensuring that the Dispense Motor and the Toner Cartridge
is engaged.
• 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.

Replace the MCU PWB.
Remove the black toner cartridge and check the Dispense Motor Assembly for wear or dam-
age.

Check continuity at both edges of the New Cartridge Detect Switch (K). There is continuity
when the Switch is not engaged.
