How do printers usually need to be maintained?

First, the internal dust removal instructions?

1, use a soft wet cloth to remove dust, stains, ink stains and scraps of paper inside the printer; ?

2. If there is too much dust, the guide shaft of the letter carrier will be poorly lubricated, which will hinder the movement of the print head in the printing process. Dry absorbent cotton swabs can be used to wipe off the dust and oil stains on the guide shaft and replenish lubricating oil with good fluidity, such as sewing machine oil. ?

Attention:?

1, don't wipe the gear, don't wipe the area near the print head and ink cartridge; ?

2. Generally, the print head should not be moved, especially for some printers whose print heads are in mechanical locking state (such as MJ- 1500K printers, needle color printers, etc.). It is impossible to move the print head by hand. If the print head is forcibly moved, the mechanical part of the printer will be damaged; ?

3, can't use paper products (such as facial tissue) to clean the inside of the printer, so as to avoid paper scraps remaining in the machine; ?

4. Volatile liquids (such as thinner, gasoline and spray chemical cleaner) cannot be used to clean the printer, so as not to damage the surface of the printer. ?
