Description: Main motor is not driving when printing, and paper does not feed into the printer, resulting 'Jam 0'.
Causes: 1. Motor harness or sub PCB may be defective. 2. Perform DCU diagnostic code 00 and Check the motor operation.
Remedy: 1. Check the motor harness, replace it, if defective. 2. Replace the SMPS, if necessary.
Code: 32
Display: No Power
Description: When system power is turned on, all lamps on the operator panel do not come on.
Causes: 1. Check if the power input and SMPS output are normal. 2. Check the inferiority of LED-Panel on the front-cover if the LED of Panel does not appear after normal warmingup.
Remedy: 1. Replace the power supply cord or SMPS. 2. Replace the control board. 3. Replace the LED-panel.
Code: 33
Display: Vertical Line Getting Curved
Description: When printing, vertical line gets curved.
Causes: 1. If the supply of +24v is unstable in the Main Control board linking with LSU, check drive by DCU Mode: LSU Check -05- LSU Motor on.
Remedy: 1. Replace LSU. 2. Replace the Main Control board.
Code: 34
Display: The printer is not working (1)
Description: While Power turned on, the printer is not working in the printing mode.
Causes: 1. Run Self-Test Mode: Turn the power on while pressing the test printing button for 2 or 3 seconds before printing works. 2. Check if the PC and the printer is properly connected and the toner cartridge installed. 3. Printing is nor working in the Windows. 4. Check if the printer cable is directly connected to peripheral devices
Remedy: 1.Check the power of the printer and perform the Self- Test. If the test printing works, that means no problems in the printer itself. If the test printing does not work, that means bad functioning of the printer(not because of software). Perform DCU to check the Error Status. 2. Replace the printer cable. If the problems not solved even after the cable replaced, check the amount of the remaining tone. (refer to Toner Cartridge Service 4-5) 3. Check if the connection between PC and printer port is proper. If you use windows, check if the printer driver in the controller is set up. If the printer driver is properly set up, check in which program the printing is not working. The best way to find out is to open the memo pad to check the function of printing. If it is not working in a certain program, adjust the setup the program requires. Sometimes, the printout is normal within the Windows basic programs, but it's not working in a particular program. In such case, install the new driver again. If not working in the Windows basic program, Check the setup of the port of CMOS is on ECP. And check the address of IRQ 7 and 378 4. If the scanner needs to be connected to the printer, first the remove the scanner from the PC to see if the printer is properly working alone.
Code: 35
Display: The printer is not working (2)
Description: After receiving the printing order, no response at all or the low speed of printing occurs due to wrong setup of the environment rather than malfunction of the printer itself.
Causes: 1. Secure more space of the hard disk. 2. Printing error occurs even if there is enough space in the hard disk. 3. Check the parallel-port-related items in the CMOS Setup. 4. Reboot the system to print.
Remedy: 1. Not working with the message 'insufficient printer memory' means hard disk space problem rather than the RAM problem. In this case, provide more space for the hard disk. Secure more space using the disk utilities program. 2. The connection of the cable and printer port is not proper. Check if the connection is properly done and if the parallel port in CMOS is rightly set up. 3. As a printer port, Select ECP or SPP among SPP(Normal), ECP, and EPP modes(increase printing speed) SPP normal mode support 8-bit data transfer, while ECP Mode transfer the 12-bit data. 4. If the regular font is not printing, the cable or the printer driver may be defective. Turn the PC and printer off, and reboot the system to print again. If not solved, double-click the printer in my computer If the regular fonts are not printed this time again. the cable must be defective so replace the cable with new one.
Code: 36
Display: Abnormal Printing
Description: The printing is not working properly even when the cable has no problem. (even after the cable is replaced) If the printer won't work at all or the strange fonts are repeated, the printer driver may be defective or wrong setup in the CMOS Setup.
Causes: 1. Set up the parallel port in the CMOS SETUP. 2. Printer Driver Error. 3. Error message from insufficient memory. (The printing job sometimes stops or due to insufficient virtual memory, but it actually comes from the insufficient space of the hard disk.)
Remedy: 1. Select SPP(Normal) or ECP LPT Port the among ECP, EPP or SPP in the CMOS Setup. 2. Check the printer in My Computer.(to see if the printer driver is compatible to the present driver or delete the old driver, if defective and reinstall the new driver) 3. Delete the unnecessary files to secure enough space of the hard disk and start printing job again.
