What's the debugging technique before the copier works
A sudden strike on a photocopy machine? The printout is either vague or cardboard, so don't rush into the maintenance! In fact, many of the problems could be solved by pre-debugging, which would not only save maintenance costs but also avoid delays in working. As a technician with eight years of experience in maintenance of office equipment, today we share the "pre-maintenance debug book" at the bottom of the box, from basic checks to advanced operations, with hands to teach you about 90% of the common problems。
I. Safety first: three steps before debugging
Before debugging, there are several security details that must not be ignored, otherwise the machine may be damaged or the risk of electrocution may arise:
1. Power outage: unplugging the power plug and waiting for five minutes for the full discharge of the cap (especially laser copiers with high-pressure internal components)。
2. Access manual: a symmetric manual focusing on the chapters "fault removal" and " daily maintenance" may have different parts of different brand machines。
3. Preparation tools: preparation of cross screwdrivers, alcoholic cotton tablets, dustless sheeting, shrubs (for processing cardboard) and avoidance of direct contact with circuit boards with metal tools。
By way of example, last year, when the client was repaired with a canyon copier, it was discovered that the other person was carrying an electric platinum drum, which caused the main plate to burn short circuits, and that the problem that could have been solved at $200 cost 1,500. Safe operations are always the first step
Ii. Basic debugging: 30 seconds to check "false failure"
Many times the photocopying machine strikes were not really bad, but these little details were not handled, and it is suggested that they be checked sequentially:
1. Material consumption status check
Powderboxes/trunk cartridges: open the front cap to observe the amount of powder, and some machines do not report any direct errors when the amount of powder is insufficient, but there will be problems with dim printing, stripes, etc。
Solve: shake the powder box to level the carbon powder (applied by lasers) or remove the powder box for re-installation (possibly poor exposure)。
Selenium drums/sensitization drums: if there are black dots or vertical wires printed, it is likely that the skin of the drums is scratched or there are carbon powder residues, with light wipe with no dust cloth (note not to touch the green sensor)。
Paper problem: 80% of cardboard and wrinkles are paper-related
Checks for damp, curly paper and recommends 70-80g standard a4 paper
The height of the paper stacks should not exceed the scale line of the paper box, and the paper edges should be aligned when loaded。
Card processing: don't use force
When the cardboard machine displays the wrong code (e. G. E000, jam001, etc.), the location of the cardboard is first found by a code hint (often in the entry, the maker, the exit):
Correct step: open the corresponding hatch, slowly extract the paper along its direction, and if the paper is broken, pull out the remaining piece of paper with a tatter (focusing on the suture of the detergent, where the temperature is high and the shredded paper is adhesive)。
Crash alert: i've seen a client rip a pictogram out of a cardboard. This part is worth hundreds of dollars
3. Restarting the law: addressing "interim failure"
Like a computer dead machine, photocopying machines encounter system disorders and try "deep rebooting":
1. Remove power plugs and hold down the opening key for 10 seconds (release static)
2. Wait 30 seconds to plug in and see if normality is restored。
Application scenario: unexpected failure to print, black screen, key unresponsive etc。
Iii. Progress debugging: targeting common problems
If the problem remains after the basic check, the following debugging techniques can be tried and a little hands-on capability is required, but the operation is not as difficult:
1. Fuzzy/coated? Calibration of print headers and scanning components
Laser copiers: enter "equipment-maintenance-print head calibration" and adjust colour alignments with tips after printing test pages
Ink-jet copiers: focus on checking whether nozzles are plugged, using a "wash nozzles" function (operated in computer-driven or machine panels) to remove water for wash nozzles (dismantling cartridges only) if there are still broken wires。
Scanning fuzzy: open the table glass, wipe the head of the scanning sheet and under the glass with an alcoholic cotton sheet (close the power!), and often the dust leads to unclear scanning。
2. Frequent cardboard? Adjust paper grinder pressure and cleaning wheel
There is a high rate of paper carding in the feeder, probably because of ageing or oily:
1. Found rubber paper-cutting vessels (usually on top of the paper box) at the penthouse to wipe the surface with wet cloth alcohol and remove oil contamination
2. In the event of serious wear and tear (fissile or smooth roads), a double-faced rubber sheet may temporarily be used to increase friction (for emergency purposes, it is recommended to replace the new cardboard wheel)。
Can't you read the wrong code? It's a good "fault code query."
Don't panic when the machine displays the wrong code
Method 1: search directly in the search engine for "brand + model + error code" such as "slash mp2014 e020" and usually find specific reasons and solutions
Method 2: calling the official customer service telephone for branding (on the manual) and providing code for the calibration of the customer service guidance is more reliable than looking for third-party maintenance。
The real case: the client's xerox photocopying machine showed "010-327" and the online search was an anomaly in the temperature of the setter, which saved $300 in door-to-door fees by restarting and cleaning the heat-sensitive electrical resistance of the seter。
Iv. Debugged "pressure testing": ensuring that the problem is solved
When the debugging is done, do not rush into use and suggest a "pressure test" to verify the effects:
1. Continuous reproduction of 10 different types of documents (text, pictures, tables) to check clarity and colour consistency
Print a black and white page to see if there are any leaks, black spots, etc.
3. Test double-sided printing and continuous paper feed to confirm whether the card paper problem is addressed。
If the test fails again, it may indicate that hardware damage (e. G., broken gears, electrical failure) is possible, and it is not late to contact professional maintenance。
Teacher's hideout: daily maintenance is more important than debugging
In fact, many failures can be avoided by daily maintenance, sharing three simple and effective maintenance techniques:
Weekly cleaning: cleaning of the body with dry cloths, painting of table glass with alcoholic cotton sheets and operating panels
Monthly inspection: opening the side cover to see if there is paper scrap, carbon powder piles in the interior and blowing dust out of the chiller
Depletion materials are cheap: non-incorporated selenium drums and carbon powder can lead to machine jamming or damage, and it is recommended to select compatible consumables for brand certification。
Finally, debugging photocopying machines is like maintaining cars, and patient check-ups always reveal problems. But when it comes to core components such as circuit boards, high-voltage plates, don't take them apart! Security is always more important than saving money. I hope these skills will help you to make less of a turn and make the copier "live."
