I use an Epson 300K II printer, why is the paper jamming constantly

Paper jams generally have the following possibilities:

1. The paper cannot be loaded correctly due to the slippage of the paper roller.

2. The paper type setting of the printer paper tray is inconsistent with the paper type set by the computer, although sometimes the printing can be completed, but only one paper can be printed, and then the paper jam is reported.

4. The last time the paper was jammed, the paper broke when it was taken out, causing a small piece of residue to remain inside the printer, which was difficult to find from the outside.

5. The sensor used by the printer to detect whether the paper passes through within the specified time sequence gives an error signal due to dirtiness.

6. The printer main control unit is faulty.

Hello! First, make sure that the thickness of the paper you are using matches where the printer paper thickness lever is placed. When printing multi-pile copy paper, the position of the paper thickness adjustment lever (i.e., 3 layers of copy paper, 3 paper thickness adjustment levers, and so on).

Secondly, please follow the following method to perform a printer self-test to confirm whether the printer has a hardware failure:

1 Make sure both the printer and the computer are turned off;

2.Load continuous paper or A4 sheet paper in the correct way in the feeder (note that the pass lever is in the correct position);

3.Press and hold the Feed Return button (or Wrap Sheet) and then press the power button to turn on the printer. When the printer is powered on, release both buttons.

Normally, the printer will print the self-test page. If paper jams persist, it is recommended that you remove the ribbon and reprint the test.

If the paper feeding and printing actions are normal, it means that the paper jam is caused by the ribbon cartridge is not installed correctly, please re-install the ribbon cartridge correctly or replace the ribbon test

If you still cannot feed paper or jam without installing the ribbon, it means that the printer has a hardware failure, please contact the Epson Authorized Service Center for further testing of the printer. You can browse the following** to see the nearest service center:

You see if there's something in your paper inlet, or you take the machine apart and clean up a line inside and try it.

Remove the screws of the print head to see if there is any dirt inside, such as ribbon slag, and see if the ribbon baffle is damaged, which is easy to cause paper jams.

1. Epson printer troubleshooting.

1. The printing format is incorrect.

2. The fault cause cannot be printed after installing the printer, and the printer interface is not opened in the BIOS of the computer.

Workaround: Go to BIOS and select IntegratedPeripherals (Port) to enter, select SuperIOdevice to enter, select ParallelPortMode to select Open, and then save and reboot, the problem is solved.

3. Unable to print the report of failure and lack of paper.

Solution: see whether the paper is installed according to the requirements, if it is installed, it will be more troublesome, you need to check whether the printer ribbon is normal, this failure is mostly caused by the distortion and winding of the printer ribbon, the ribbon is down, and it can be reinstalled after adjustment.

4. Turn on the power switch of the printer, the printer "quack, rattle" sounds, the printer "squeak, squeak" alarm, and cannot print online.

Solution: It is related to the use environment of the printer, as long as the power is cut off, then wipe the shaft clean with soft paper, and then drip the sewing oil, repeatedly move the print head to wash out and wipe the dirty, and finally drip the oil on the clean shaft, and move the print head by hand to make the distribution even, and the machine can work normally when it is turned on.

5. The printed characters have few shortcomings, or the chassis is conductive.

Solution: It is caused by the wear and tear of the flat data cable of the printer print head, and the flat data cable can be replaced.

6. The print head is broken.

Solution: The easiest way is to run the needle break detection program, such as running the needle break detection and repair exemption program under UCDOS, which can be detected and exempted from repair for only a few needle breakage cases. For a large number of broken needles, it is necessary to replace the broken needles.

7. Even if the print head is good, the characters typed are not very refreshing, especially when printed on wax paper.

Solution: If the printer has been used for many years, and the parts have been offset, or the circuit components of the printer are aging, as long as the printer is disassembled, and the potentiometer that controls the strength of the printing needle can be adjusted appropriately.

First of all, observe whether the paper is wet, the paper should be changed when the paper is wet, see whether the paper is installed according to the requirements, if it is installed, it will be more troublesome, you need to check whether the printer ribbon is normal, this failure is mostly caused by the distortion and winding of the printer ribbon, put the ribbon down, adjust it and reinstall it. If it doesn't work, you can wipe the shaft clean with soft paper, then drip the sewing oil, repeatedly move the print head to wash out and wipe the dirty, and finally drip the oil on the clean shaft, move the print head by hand to make the distribution even, and the machine can work normally when it is turned on.

Hello, the reason for the paper jam in the Epson printer is that the paper roller is not good. Reasons: 1. Paper jam in the paper feeding part (due to the bad paper roller, bad paper loss, foreign objects in the paper path, and bad paper feeding sensor) 2. Stuck in the middle part (bad alignment roller, bad paper path sensor) 3. Fixing jam (bad separation claw, bad paper output sensor, bad fuser itself, bad paper output roller) The operation method is as follows:

1.Remove any remaining paper from the feeder and open the feeder cap. 2.

Gently remove the jammed paper from the feeder. 3.Close the feeder lid and reload the removed paper (if any) into the feeder.

4.Open the scanner cover, grasp the mis-sent paper, and carefully pull it to the right with both hands to remove it from the paper feed area. 5.

Close the scanner cover and reload the removed paper into the feeder.
