Fault White Black spot

Signs Light or dark black dots on the image occur periodically.

Cause & Check

Solution 1. In case of 1 above Run OPC Cleaning Mode Print 4-5 times repeatedly to remove. Especially check foreign substance on the OPC surface, then remove them with a clean gauze moistened with IPA(Isopropyl Alcohol) not to damage OPC if necessary. Never use usual alcohol. 2. In case of 2 If they are not disappeared by running OPC Cleaning Mode Print 4-5 times. : at intervals of 37mm - Replace the developer. : at intervals of 75mm - Remove foreign substance. : Broken image - Replace the developer according to carelessness. 3. In case of 3 - Exchange the transfer roller because the life of the transfer roller in use has been expired. (Check the transfer voltage and readjust if different.)
1. If light or dark periodical black dots occur, this is because the developer rollers are contaminated with foreign substance or paper particles. White spots occur in the image period- (1)35mm interval : Charged roller ically. (2)75mm interval : OPC cycle
2. If white spots occur in a black image at intervals of 75mm, or black spots occur elsewhere, the OPC drum is damaged or foreign substance is stuck to the surface.
3. If a black and white or graphic image is partially broken at irregular intervals, the transfer roller's life has been expired or the transfer voltage is abnormal. Recycled product Poor appearance of 1. Poor appearance of the develthe developer. oper. (1)Check the damage to label Unclean and rough and whether different materiprintouts. als are used. (2)Check the appearance of Bad background in parts of the developer, such the image. as frame, hopper.
1. In case of 1 (1)If there is an evidence of disassembling the developer. (2)If materials other than normal parts of the developer are added or substituted.
2. Unclean and rough printouts. (1)Check whether foreign substance or toner are stuck to the terminal (contact point) of the developer. (2)Check whether the state of the terminal assembly is normal.
2. In case of 2 - If there are any abnormals in connection with the situation of 1. (1)It occurs when the developer is recycled over 2 times. (2)If toner nearly being expired are collected to use, it is judged as the recycled developer.
Fault Ghost & Image Contamination
Signs The printed image is too light or dark, or partially contaminated black. Totally contaminatedblack. (Black image printed out) The density of printouts is too dark and ghost occurs.
Cause & Check 1. The printed image is too light or dark, or partially contaminated black. (1)Check whether foreign substance or toner are stuck to the terminal(point of contact) of the developer. (2)Check whether the terminal assembly is normal.
Solution 1. All of 1, 2, 3 above (1)Remove toner and foreign substances adhered to the contact point of the developer. (2)The contact point of the unit facing that of the developer also must be cleaned. (3)If the terminal assembly is unsafe: Fully stick the terminal to or reassemble it after disassembling. Disassemble the side plate and push the terminal to be stuck, then reassemble it. 2. In case of 2 It is a phenomenon when the OPC drum of the developer is not electrically charged. Clean the terminals of the charged roller, then recheck it.

2. Totally contaminated black. (Black image printed out) (1)Check whether foreign substances are stuck to the terminal(point of contact) of the developer and the state of assembly. (Especially check the charged roller terminal.)
3. The printed image is dark and ghost occurs. (1)Check foreign substance attached to the terminal (point of contact) of the developer and the state of assembly. (Especially check the developing roller terminal.)
3. In case of 3 It is a phenomenon as the developing bias voltage of the developer. Clean the terminals of the developing roller, then recheck it.
4-6 The cause and solutions of bad environment of the software
4-6-1 The printer is not working (1)
Description While Power turned on, the printer is not working in the printing mode.
Check and Cause 1. Run Self-Test Mode: Turn the power on while pressing the test printing button for 2 or 3 seconds before printing works.
Solution 1.Check the power of the printer and perform the SelfTest. 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
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
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.
4-6-2 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. Check and Cause 1. Secure more space of the hard disk. Solution 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.

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.
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. Reboot the system to print.
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.

4-6-3 Abnormal Printing

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. Check and Cause 1. Set up the parallel port in the CMOS SETUP. Solution 1. Select SPP(Normal) or ECP LPT Port the among ECP, EPP or SPP in the CMOS Setup.

2. Printer Driver Error.

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. 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.)
3. Delete the unnecessary files to secure enough space of the hard disk and start printing job again.

4-6-4 SPOOL Error

To spool which stands for "simultaneous peripheral operations online" a computer document or task list (or "job") is to read it in and store it, usually on a hard disk or larger storage medium so that it can be printed or otherwise processed at a more convenient time (for example, when a printer is finished printing its current document). Check and Cause 1. Insufficient space of the hard disk in the directory assigned for the basic spool. Solution 1. Delete the unnecessary files to provide more space to start printing job.
