Maintenance methods for common failures of fax machines
1. When sending faxes, the originals often appear skewed or even jammed
When the original is being transmitted, it is either skewed or the original is jammed. You should check whether the two shafts of the paper transmission part inside the fax machine have been loosened in time, because once the two shafts are loose, they will not be affected. With enough pressure on the paper, the paper can easily become skewed or even jammed. Therefore, if the two stick shafts are found to be loose, the two stick axles should be cleaned and adjusted immediately to restore the two stick axles to their normal working state; if the two stick axles are not installed in parallel, it will easily cause the above faults, so everyone must Make sure that the positions of the two rollers are parallel, and that the position of the original guide plate is correct or not, it will also affect the transmission of the original.
Therefore, before the document is sent, the position of the original guide plate must be adjusted correctly, and the document to be sent must be placed neatly on the guide plate; in addition to the above factors, the paper conveying path Obstacles on the fax machine can easily block the normal transmission of the original, resulting in paper jams or jams. Therefore, once a paper jam occurs, you should also remember to open the side panel cover of the fax machine in time to remove the paper scraps on the paper transmission path. or other obstacles are removed.
Second, the fax machine will transmit multiple pages each time
Each time multiple page transmission is a very common and very common failure phenomenon, causing There are many possible reasons for this failure. For example, once the transmission metal plate of the paper conveying part is deformed, this failure will occur. Therefore, once the transmission metal plate is found to be deformed, it should be adjusted immediately or even replaced with a new one. If the face cover of the fax machine is not properly covered, it is easy to cause the failure of each multi-page transmission.
Therefore, before sending a fax, you should first carefully check whether the face cover of the fax machine has been covered; in addition to the above two reasons, the quality of the paper separation rubber sheet directly affects the correct transmission of the original. , If the separation rubber sheet is damaged or the surface is dirty, it should be replaced in time or cleaned with detergent.
Three, When faxing or printing, the paper is all white
If your fax If the machine is a thermal fax machine, the front and back sides of the recording paper may be installed incorrectly. Please put the back side of the recording paper and try again. The fax paper used in thermal fax machines has only one side coated with chemicals. So the installation is wrong and no text or pictures will be printed out when receiving faxes. If your fax machine is an inkjet fax machine, the nozzle head may be blocked, please clean the inkjet head or replace the ink cartridge.

When the document sent to you or the document printed by yourself during copying appears one or more lines black line. If it is a ccd fax machine, it may be that the reflective lens is dirty, and if it is a cis fax machine, it may be that the transparent glass is dirty. Please clean it with a cotton ball or a soft cloth dipped in alcohol according to the instructions in the fax machine manual. If the problem cannot be solved after cleaning, please send your fax machine for repair.
5. White lines appear on the paper when faxing or printing
White lines appear on the paper when faxing or printing, usually due to the thermal head (TPH) Broken wire or stained with dirt. If the wire is broken, the thermal head of the same type should be replaced. If there is dirt, it can be removed with a cotton ball.
6. The paper cannot be fed out normally
Please check that the feeder is blocked by foreign objects, the original position scanning sensor is invalid, and the gap between the feed rollers is too large. big wait. In addition, check whether the sending motor rotates. If it does not rotate, check whether the circuit related to the motor and the motor itself are damaged.
