Epson 680k2 dot matrix printer, sometimes the fonts are duplicated together

Print overlap can be caused in part by a problem similar to a paper jam on the printer.

Here are some how-tos on paper jam issues that you can refer to.

Please make sure that the "Out of Paper" and "Pause" indicators are not always on or flashing when the printer is turned on normally, if these two indicators are on or flashing, such as OKI products, please refer to the random "Operation Manual" for troubleshooting.

Also, make sure that the paper is loaded correctly as follows:

When using a sheet of paper: Turn on the printer, place the pass lever on the sheet position, swipe the paper rail to align with the triangle marker, and insert the paper along the rail until resistance is encountered.

When using continuous paper: Place the paper pass lever in the continuous paper position and move the feed rail of the feed sheet to the far left; Slide the left chain tooth on the rear of the printer so that the chain tooth is facing the left arrow mark (0 position), slide the right chain tooth so that it roughly matches the width of the printing paper, load the continuous paper, slide the right chain tooth to flatten the paper; Then press the sprocket lock lever to secure the right sprocket teeth.

Note: When printing multiplex copy paper, make sure that the paper thickness lever is placed in the same position as the number of copies.

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 you can't feed and print normally, it means that the printer has a hardware failure, please contact OKI after-sales service, they have a warranty of more than 3 years.

It is possible that the feed roller and the paper wheel are aging.

You can enter the printer's settings screen to select the correction print head.

Since each brand of printer has its own correction method for drivers and printheads, there is no standard method for questioners to refer to.

However, just find the interface for correcting the print head and follow the step-by-step wizard provided by the driver.

1. The solution of printer printing dislocation After using the dot matrix printer for a period of time, there is often a fault of printing dislocation, which is generally caused by the drying of the lubricating oil on the shaft where the print head is located.

2. The correct solution is: first wipe the original lubricating oil and stains on the shaft with a clean towel or paper towel dipped in a little gasoline or sewing machine oil, and then wipe the shaft with a towel or paper towel dipped in a certain amount of lubricating oil, wipe while moving the print head, repeat several times, until the shaft is evenly smeared with lubricating oil, and the print head can move lightly and effortlessly.

3. It is recommended to use silicone oil for copiers, if not, ordinary sewing machine oil and light engine oil can also be used. In an ordinary office environment, it is enough to deal with it once a year.

4. Some machines may also cause this failure because of the aging or loosening of the print head drive belt, this kind of inspection method is very simple, pull the belt by hand, if you feel that the belt is aging and stiff or abnormally loose, just replace or fasten it.

There are several reasons that can cause this failure and should be troubleshot by following the steps below:

1. Print the printhead test page to see if there is any missing line or oblique spraying.

2. If there is a broken line or oblique spray, run the print head cleaning program.

3. If not, run the printhead calibration program.

4. If the printing is normal after calibration, complete the operation.

If it's still not working, follow these steps:

1. Open the upper cover of the printer.

2. Above the belt of the printing ink car, there is a flat translucent plastic strip, which is called "grating".

3. Clamp the grating with 2 cotton swabs dipped in water (operate carefully, you need to find the trick slowly), and wipe it clean left and right.

4. Wipe again with a clean cotton swab.

5. Complete the operation.

Note: Only water can be used, not corrosive liquids, because the grating is extremely precise, 1 mm has a lot of grids, you must pay attention, because there is a spring on one side to fix, you can pull slightly when wiping, do not use too much force.

Try printing the test page on A4 paper first. If the test page is fine, the printer is fine. You set up the software. and the format of the paper and so on.

If there is a problem with the test page. You can see if the driver is native. Or try to reinstall the driver.

Wipe the paper stick, is not caused by slipping.

This has to be set up in the software, depending on what software you use.

Let's see if the print size is A4.

Hello. Depending on your problem, please adjust the test as follows:

Please check whether the printer will have abnormal sound or the print head hitting the sidewall during the printing process, if it is likely that the printer has a hardware failure, please browse the following**Contact the nearest Epson authorized service center for further testing of the printer:

If there is no abnormal noise or head banging, please check whether the printed content is offset from top to bottom or left and right.

If it is an up-and-down offset, please try to adjust the top margin of the page in the software first, if the adjustment is invalid or cannot be adjusted, (if the width of the printed content is above), you can install the LQ-1900KIIH driver from the following Epson **** and adjust the printing position as follows: "Control Panel" - >Printers & Fax" or "Devices and Printers", right-click the 1900KIIH printer icon and select "Printing Preferences" - >Extended Settings", Adjust the vertical offset (if you need to adjust it up, set the vertical offset to a negative value, and vice versa down).

If the printing problem persists, it is recommended that you change the Word or Excel printing test, if the printing is normal, it should be that there is a problem with the application software you are using, please check the upper and lower margins in your software or contact the software developer. If the same problem exists with word or excel printing, it is recommended that you change the computer for testing, or you can contact an Epson authorized service center to test the printer. You can browse the following** to see the nearest service center:
