• Code: 18
• 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 and pressing “System Data List” by pressing Menu-Reports-System Data. 2. Check if the PC and the printer is properly connected and the toner cartridge installed. 3. Printing is not working in the Windows. 4. Check if the printer cable is directly connected to peripheral devices
• Troubleshooting Guides: 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). 2. Replace the printer cable. If the problems not solved even after the cable replaced, check the amount of the remaining toner. 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: 19
• 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.
• Troubleshooting Guides: 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: 20
• 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.)
• Troubleshooting Guides: 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.

• Code: 21
• Display: SPOOL Error
• Description: 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).
• Causes: 1. Insufficient space of the hard disk in the directory assigned for the basic spool. 2. If the previous printing error not solved. 3. When expected to collide with other program. 4. When an application program or the printer driver is damaged. 5. When some files related to OS are damaged or virus infected
• Troubleshooting Guides: 1. Delete the unnecessary files to provide more space to start printing job. 2. If there are some files with the extension name of ****.jnl, Delete them and Reboot the Windows to restart printing job. 3. Shut down all other programs except the current one, if possible. 4. Delete the printer driver completely and reinstall it. 5 After rebooting the computer, check for viruses, restore the damaged files and reinstall the program to do the printing job.

If faded areas or voids occur in a black image at intervals of 75.5 mm, or black spots occur elsewhere, the OPC drum surface is damaged. 3. If a black image is partially broken, the transfer voltage is abnormal or the transfer roller’s life has expired.
• Troubleshooting Guides: 1. Run OPC cleaning Mode Print and run the Self-test 2 or 3 times. 2. In case of 75.5 mm interval unremovable in 1, cleanly remove foreign substances stuck on the OPC location equivalent to black spots and white spots with a dry duster. 3. The transfer roller guarantees 50.000 sheets printing. If the roller’s life is expired, replace it. 4. In case of 37.7 mm interval unremovable in 1, take measures as to replace the developer cartridge and try to print out. 5. Clean the inside of the set against the paper particles and foreign matter in order not to cause the trouble.

Samsung printer reset software introduction:

Notes before resetting Samsung printer:

– Identify accurate version, serial and crum of Samsung printer.
– How to get Samsung printer model info: Click Here
– Before you continue with the reprogramming of the firmware, please make sure that the device is installed on your computer.
– It is very important that under no circumstances should you remove the chip from the cartridge while reprogramming the firmware. After you have succesfully reprogrammed the printer, remove the chip from the cartridge and store it somewhere safely (the chip – a key). In all cartridges which you are going to use in the printer, the chip has to be either removed or sealed. If you have accidently inserted a new cartridge without removing the chip, the device will be blocked. In order to unblock it, you can use the stored chip as a key which help you to unblock the printer.
– And make sure that any other devices (except mouse and keyboard), which are connected to your computer via USB or LPT ports are disconnected. It’s preferable that the computer is connected to the “UPS” (uninterruptible power source) device, because if during the reprogramming process the electricity source has any interruptions, then the reprogramming will be carried out with an error, which makes the device unable to work.
– This firmware will be installed directly to your printer. Before opening firmare link make sure that printer is turned on and connected to your computer and printer drivers are installed correctly.
Be aware that with the reprogramming of the firmware the manufacturer’s warranty goes lost!!

How To Run Firmware Fix Samsung printer

1. Connect the printer to the computer and turn it on.
2. Wait until the printer is ready for work.
3. Drag and drop *.hd to usbprns2.exe file.

4. The reprogramming process starts automatically.
5. Wait until the printer reprograms (10-20 minute) and restarts.
6. After that the reprogramming process is finished, restart the printer.
