Instead, waste toner sensor offset adjustment is performed bythis adjustment (high-voltage offset adjustment). Therefore, when replacingthe waste toner sensor, execute this adjustment service mode. If toner is leftinside the waste toner bottle here, toner adjustment cannot be carried outproperly, resulting in an error code in some cases (E0013-0006: waste tonersensor adjustment error). Be sure to execute this service mode after removingthe waste toner bottle from the main body.13.3.9 After Replacing the ATR Sensor 0014-8932imagePRESS C1 P / imagePRESS C1 / imagePRESS C1+ (Printer) / image-PRESS C1+Follow the procedure below to replace the ATR sensor.1) Replace the color developing assembly (Y, M, C).2) Turn on the main power switch.3) Run automatic gradation correction (full correction).When Installing the ATR Sensor* Be careful not to touch the developing cylinder, which can cause imagefault.Upon installation of the ATR sensor, make sure to move the developing cyl-inder away from the mounting location of the sensor by rotating the devel-oping rotary clockwise.* When plugging in the connector [1], wrap the harness [3] around the wiresaddle [2] once.F-13-1513.3.10 After Replacing the Patch Image Reading Sensor0014-8933imagePRESS C1 P / imagePRESS C1 / imagePRESS C1+ (Printer) / image-PRESS C1+Run the following items in the Service Mode after replacing the patch imagescan sensor.Service Mode (Patch Detection Sensor Default Correction) :COPIER > ADJUST > DENS > ALF-F (front)>COPIER > ADJUST > DENS > ALF-C er)>COPIER > ADJUST > DENS > ALF-R This sensor unit comes with the following correction value labels (3 in total).The labels contain correction values for each sensor (front, center and rear).Enter the label values (4 digits) [1] using the above service mode.After entering the values, put the labels onto the new sensor unit.F-13-1613.4 Fixing System13.4.1 Checking the Nip Width 0012-0899imagePRESS C1 P / imagePRESS C1 / imagePRESS C1+ (Printer) / image-PRESS C1+The nip width cannot be adjusted at the field.When replacing the fixing belt/fixing roller, or a fixing failure occurs, checkthat there is no problem with the output result of the nip width (COPIER >FUNCTION > FIXING > NIP-CHK).1. Set a duplexing coated paper (equivalent to 120 to 128 g) in the manualfeed tray.2. Execute the foregoing service mode.3. Measure the nip width of the output paper (cyan solid image).4. Check that the nip width(A,B) is within the range of reference values(4.5 mm +/-1).[1][2] [1][3][1]
