Case Analysis: Common Faults Engineer Xiangjie Copiers - Copiers Failure - Office Supplies Industry

For Duplicator , The copy quality and paperboard machine failures are common failures

, and sometimes these failures it is very simple and some are false failures, but users do not know how to determine the treatment, precisely because of these small faults, affect the work efficiency, following through on a number of maintenance engineers I summarize the experience, to provide some authoritative point of view, we want to help after the use of photocopiers.

Common cardboard failure Copier jams occasionally, not failure, but if frequent paper jams, you need to check the maintenance of the. First of all, be clear in which part of paperboard, paper for the site is taking part paper, or snapshot site?, Of course, significant parts of these three parts, if damaged, can change. However, many situations in which the transmission sector without any apparent damage to parts, and no obstructions, but frequent paper jams, it will affect efficiency, but also affect the operators of mind. On the maintenance staff is sometimes intertwined with several factors often affect the diagnosis.

1. Paperboard parts for the paper: This part of cardboard, covered is larger, should first check whether the paper used in standard (such as paper weight, size, dry level), try to use standard paper machine . Boxes do not behave, also contributed to the reasons for cardboard. Can be to try, just put a few in paper cartons, and then take the paper, if the twist does not enter or not in place, can be determined is the rubbing roller clutch problems or rubbing paper; if rubbed on paper in place, but the paper can not continue to move forward is estimated is a bit roller clutch slipping or failure caused by bit. For some models, twist paper appears skewed, both sides of the carton may be caused by clamping force sizes. In addition, many operators put in the plug tray, the force is too large, resulting in several sheets of paper from the tray above the claw, it will inevitably lead to paper jams.

2. Take the position paper jam: If the regular jams in this area should be by means of the door switch plate (a tool), carefully observe the functioning of this site, the exclusion of the belt, guide wheel of the factors is should check the separate agencies. Because different copier models, their separation in different ways, to be treated differently. At present, several domestic popular models, the separation of roughly three ways: negative pressure isolation, separation with separation, charge separation. Specific inspection and maintenance methods, not repeat them here.

3. Paperboard fuser parts: fuser roller separation claws when, after prolonged use, the tip blunt or after a small spring fatigue failure will cause jams. For some models, the paper roll feeding the mouth of serious wear and tear after prolonged use, would frequently jam. The fuser roller serious scaling resulting from the cardboard, models are common in the general case.

By paper path sensor failure or other circuit failure caused by cardboard, a different kind of problem, should control the maintenance manual, the help of instruments, make the appropriate checks.
