Quick Copier Repairman 10 Minutes
Jamming: Copier Occasional paper jam, not a fault, 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, these three sites of apparent damage to any parts, and replace. 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, for paper, cardboard parts: the 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, there is no longer Cheung stated.
3, parts of paperboard fuser: 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.
4, because paper path sensor failure or other circuit failure caused by cardboard, is another question, should control the maintenance manual, the help of instruments, make the appropriate checks.
Copying products without images: Such failure occurs, first for routine inspections to check the master tape with electrical appliances and transfer is obvious damage, such as the corona wire Bengduan, Plastic Parts breakdown, etc., there are photosensitive drum is turning, how the scanning lamp brightness. At the same time, also asked the operator type of toner used, add the vector of the time and so on. Exclude the above factors, should be done the following: Open the front cover, switch plate with the door switch connected to copier in a normal power state. Put away the glass original, turn away paper, paper delivered to the photosensitive drum when the bottom, turn off the machine, remove the imaging drum, drum check whether there are images, if image shows part of the problem lies in the transfer, such as No images to illustrate the problem lies in the main part and imaging with electrical parts.
Of the transfer part and the main part of the trouble with electrical appliances, have a corresponding check processing methods described here are no longer Cheung. Develop part of the failure, there are two main reasons: (1) imaging roller drive clutch failure, developing roller can not rotate, it may be due to improperly adjusted, resulting in between the blade and the imaging roller gap is too small, causing the clutch does not bring the imaging roll rotation. (2) on some models of copiers, such as NP-270, imaging device is a locking lever pressure by leaning on the photosensitive drum (to maintain a certain gap), as the operator turned the lock lever, the action too fast and too, causing locking rod twisted, can not lock imaging devices, imaging drum roll and the gap is too large, the toner can not be adsorbed to the photosensitive drum, is showing up blank copy.
Above, the only fault in the two cases of copier. In fact, the copier failure varied, and some failures, according to their own self-diagnostic function copiers can be determined. Some fault must be observed, analyzed, to determine. The face of a faulty copy machine, how to make a correct diagnosis and repair it as soon as possible? Following is a more appropriate.
