Generally speaking, the contents of scans and faxes are blurred for several reasons:
The scanned manuscript is improperly placed, with corners or uneven folds.
The file was moved during scanning.
The resolution setting in the scanning options is incorrect. The higher the scan resolution, the clearer the image.
The resolution of the printout is set incorrectly, and the file size is set incorrectly.
The scanned manuscript is not clear enough, and there is dirt on the glass manuscript table, so the scanning effect will be worse. Clean with paper towels that can't remove debris in time.
The printer scanning head is faulty, so it is recommended to contact the maintenance center to check whether there is any problem with the machine hardware.
How to clean the scanning component and solve the fuzzy problem;
Press the power switch to turn off the all-in-one machine. Remember to turn on the power switch if replacing consumables such as toner cartridges.
2. Open the manuscript support of the automatic document feeder and clean the white plastic strip with a soft, lint-free wet rag. Remember to clean the up-and-down scanning components of the all-in-one machine with double-sided scanning function.
3. In addition to the document feeder, the multifunctional machine is equipped with a flat plate for cleaning, a flat plate scanner for cleaning with a soft lint-free wet rag, and an automatic document feeder unit located above. Finally, turn off the automatic document feeder and document table, and turn on the power switch to start the machine.

The most common faults of printers
First of all, the printer is broken.
1. There is no response when booting.
2. After starting the machine, the indicator light flashes.
3. The light comes on after the machine is turned on, but it doesn't.
Reasons for the above phenomenon: In general, printers are basically equipped with over-current protection devices. When the current is too large, the printer will be over-protected and the fuse of the printer will be blown.
Second, the effect of printing, copying and faxing is poor
1. The color of text and pictures becomes lighter, which may be caused by uneven toner or lack of ink in the printer, or by printing settings.
2. There is a black print on the paper, which may be that the OPC material on the drum core of the printer toner cartridge has fallen off, and the toner cartridge needs to be replaced.
3. White stripes appear on the paper
Third, the printer is out of paper.
1. No paper feed.
2. Paper jam
Feed multiple sheets of paper
The printer does not feed paper. Reason:
There is too much printing paper. Check whether the quantity of printing paper meets the standard. If it exceeds the quantity, please reduce the printing paper.
The printer is blocked by foreign objects. Check the printer for foreign objects, such as paper jams.
Printing paper is wet. If it is stored for too long or improperly, the surface of the paper will also be wet. Just dry the printing paper.
Whether the printer runs out of ink or not, the indicator light of the printer's black or color ink cartridge will flash or shine straight to indicate that the ink is about to run out. If the printer cartridge is empty, the printer can't feed paper.
Printer paper jam reason:
Whether the surface of printing paper is flat or not, paper is prone to paper jam when it is curled or wrinkled. It is best to use paper with a flat and smooth surface, and there can be no sticky attachments on the surface.
The printing paper is too thin or too much. Under normal circumstances, the quality of printing paper is more than 60 grams to print normally. Too thin paper will cause the printer to jam. Paper jams can also occur when too many printing papers are loaded at one time.
The delivery roller is worn, which is the most easily worn part of laser printing. When the paper in the paper tray is normal and it is impossible to take paper, it is often that the delivery roller is worn or the spring is loose, which needs to be solved by a professional maintenance master.
The printer feeds multiple sheets of paper at the same time. Reason:
The printer sucks in two or more sheets of paper at a time. It may be that the paper is static and cannot be separated.
The separator in the paper feed section is faulty. The separator consists of a separator plate and a spring. Check whether the spring is not elastic enough, and replace the faulty parts.
