Display: Insert Black Print Cartridge Error 093-973
Description: <IOT K CRU Detached> The black toner cartridge detached is detected.
Remedy: 1 Check that the black toner cartridge is correctly installed and in the black position. Is the black toner cartridge installed correctly? Go to step 3. Go to step 2. 2 Reinstall the toner cartridge. Does the error still occur when the power is turned on? Go to step 3. Problem resolved. 3 Replace the black toner cartridge. Does the error still occur when the power is turned on? Go to step 4. Problem resolved. 4 Check the toner sensor: 1. In Service Mode, select Printer Diag. 2. Select Engine Diag, and press OK. 3. Select Sensor Test, and press OK. 4. Select CRU Sensor K. OFF appears on the display. 5. Open the front cover. 6. Press OK to begin the test. 7. Toggle the black CRU sensor by opening the front cover and removing and replacing the black toner cartridge. If the sensor is functional, the initial L - O increments by one whenever the sensor is activated. Does the number on the screen increase by one every time the toner cartridge is reinstalled? Replace the controller board. See “Controller board removal”. Go to step 5. 5 Check the P/J19 and P/J193 connectors between the controller board and toner cartridge assembly. Are the connectors (P/J19 and P/J193) connected securely? Go to step 6. Reconnect the connector(s) P/J19 and/or P/J192, then go to step 6. 6 Does the error still occur when the power is turned on? Go to step 7. Problem resolved. 7 Disconnect the P/J19 connector on the controller board. Measure the voltage between J19-7 pin and the J19-8 pin. The voltage should measure approximately +3.3 V dc. Is the voltage between J19-7 and J19-8 pins approximately +3.3 V dc? Go to step 8. Replace the controller board. See “Controller board removal”. 8 Measure the voltage across ground and the P/J19-9 pin. Check that the voltage changes when the paper is inserted into the sensor detecting point. Does the voltage change when paper is inserted? Replace the controller board. See “Controller board removal”. Replace the toner sensor assembly.
