Adjustment LQ-2070 Service Manual 4.2.4 TPE Level Reset This section describes the procedure to reset the TPE (top paper end) level. This operation is required when the PW sensor assembly is replaced, and if it is not performed, the printer does not recognize that the PW sensor has been replaced, which limits the ability of the new sensor to operate. This reset operation can be performed only from the Settings Diskette. Note: • After this operation, the reset value for the TPE LEVEL is printed out automatically. Check that the reset value is FF. • When you run Check Pro. from the Main Menu after running the TPE LEVEL RESET, the TPE LEVEL is not printed for "FF." This is because the measured TPE level has been overwritten in the EERPOM. This is no problem unless an extremely low TPE LEVEL is printed as the Check Pro. result, despite the PW sensor's having been replaced and the TPE LEVEL being reset. If this occurs, replace the PW sensor again. 1. Insert the Settings Diskette into Drive A of the PC, and turn the power on. 2. Type GWBASIC and press ENTER. 3. Load and run the J10A30E program.
