HP mid range and higher printers are considered work horses.  they are designed for easy printer fax copier repair and installation of maintenance kits.   However, thee are some exceptions to the rule.  The HP 4250 and HP 4350 series laser printers are work horse, but one with a problem- swing arm gear.  Repairing the printers  normal problems such as paper feed issues and fuser assemblies are simple just like there previous models the HP 4200 and HP 4100 laser printers.  However, HP designed the drive gear/swing plate with a flaw: its plastic, it wear out often and you need to tear apart the printer in many pieces to repair.

The repair of the HP printer swing plate requires the removal of the coverings, circuit boards and other parts which takes an experience printer repair technician about an hour to complete.  Most technicians when learning how to do this repairs take 2 hours or more to do it.  It’s imp[important that you specify that you want a technician who has a proven repair record when doing this repair. It’s not  simple repair.  You will need to provide a good size printer repair work area the removal of the parts.

Also when repairing the swing plate of the HP laser printer you may need to replace the fuser assembly at the same time. The fuser assembly is a swap HP printer repair part that only takes a few minutes to accomplish.

Brother toner based MFC have been in the forefront of the multi-function all in one printer scanner copiers for the since the nineties long before Hewlett Packard  and other brands.  Brother produces good quality toner based small off and home based office printer copiers that have always preform well. Brother MFC ink based ones are very popular due to low cost. This article covers the toner based MFC color all in one repair maintenance image problems.

Repairing and performing maintenance on the Brother color copier printer scanners is not difficult if you know the steps to take. First, is to determine the cause of the problem. Just like when repairing HP, Lexmark and other copier printer scanners use the process on elimination. All color printer copiers contain four toner cartridges, a set of drums, imaging unit and fuser. Depending upon what the actual image repair maintenance problem looks like will determine which part to replace.

If the printer copier repair image problem only effects one color (black lines on color pages, or getting blue streaks/spots but not yellow, black or magenta, etc.) then you can eliminate the imaging unit and the fuser as the problem.   On the Brother MFC 9840, 9440 and similar models it uses one drum unit and four separate toner cartridges.  If you are only having problems with the cyan (Blue) then you either need to replace the cyan toner or the drum unit.  If the printer repair image problem is a yellow line then its the yellow toner or drum unit. If you are having a black line then things are a bit different because the problem can be the fuser too.

Now if the image problem does not follow and one particular problem then the cause could be the drum, image unit or the fuser. Print out several pages and see if the image problem is a pattern (repeats two or more times per page) or is a print repair maintenance problem along the whole page.  The image unit rotates once per page, the drums approx 3 times and the fuser 5 times per page.

The next step is to pull out the image unit, drum unit and he fuser and try to match the printer image problem with the actual unit.  If your technician has repair and performed printer copier maintenance repair worked on the Brother and other brands such as HP, Lexmark, Ricoh and canons then over the phone they should be able to diagnose the problem with 97% accuracy without you spending a dime of your money upfront.  If they can not give you an idea and you are in South Florida contact Advanced Business Computers printer copier repair department.

PAPER JAMS

95% of all paper jam repair maintenance problems with printer scanner copiers MFC  occur in three places: (1) ADf automatic document feeder on the top of the unit,  (2) in the plain paper drawer and (3) in the fuser area paper getting stuck drum the drum area.  The printer copier repair for the first two areas are not expensive repairs. They both require replacing the paper pick up assembly or roller and the paper separation pad or assembly. In fact, on some Brother MFC the printer copier scanner repair needed i indicated on the LCD “replaced PF1 fit” or “replaced PF2 kit”.  Both the PF1 and PF2 brother paper repair maintenance feed kits are USER replaceable. You do not need a technician to do the repair 95% of the time if you ave basic skills with a standard screw driver.

The Brother MFC fuser repair paper jam problem is a bit more expensive to repair. The fuser assembly on all brands of printers copiers scanners are considered normal wear and tear parts. In other words, they wear out over time and require repair or replacement.  ON some printer copier scanner fax machines repairing the fuser is as simple as removing a couple of screws. On other brands it requires you to remove covers, power supplies and other components.  On large copier printer new fuser as so expensive that most technicians rebuild them and the manufacturer offers a copier printer maintenance kits that contains all the parts to repair rebuild the fuser assemblies.  The Brother MFC printer copier scanners fuser are not rebuilt but just replaced as a unit.  Most Brother MFC’s fuser copier printer repair maintenance take an technician lessthan 30 minutes to complete.

You will notice several of copier printer repair errors are very similar.  Many times several repair copier printer maintenance codes point to the same problem in different ways. Example are the pressure roller error codes related to the temperature which indicates that he thermal control parts of the fuser assembly of the printer copier need to be replaced. In some models this entails the actual replacement of just the thermistors. Advanced Business Computers is very experienced in the repair of copier printers scanners in the Southeast Florida areas. If you need further help in determine what an error code means please post a question here on this blog.

One of the most common problems beyond the regular HP maintenance repair kit installation is the failure of laser printers communication with the network.  If you HP printer, Lexmark laser or other laser printer fails to print a job then you need to check your communications.   On a network when you send a print job it goes through your switch to the laser printers Nic (network) card (HP jetdirect) and then to the laser printer copier formatter board.

The first item to check when repairing your Hp printer problem is your network cable on your printer copier to make sure its seated well in the printer and the network switch.  At the same time check to see if your NIC card (HP jetdirect card) shows a green light.  If the card does not show a green light then it is not communicating with the network or the formatter card in the printer. If this happens first install a new NIC card to repair the printer copier problem. IF the new card still does not show a light then either the formatter is bad or the network connection.

If you have a second network printer then take the network cable out  of the printer having the repair problem and put it in to the other printer to eliminate the switch and network cable as being the printer repair problem. If the cable works in the other printer then you know you will need to replace the formatter and possibly the jetdirect card.  If the connection does not work on the other printer then you have a network problem (bad cable, switch, other).  Repairing printer copiers communication problems is a process of elimination.

When repairing your HP printer or other brand copier printer  make sure you follow logical steps in eliminating possible printer failure to communicate problems.

This is going to be a shorter post on printer repair of for HP, Lexmark, Kyocera and other laser printers.  Many times during the year clients call with a common problem when when they use more than on size of paper. Its the HP repair size mis-match problem. This error occurs when the laser printer receives a command from the computer to print on a size of paper not in the paper cassettes or the MP tray (tray 1).  First, this is not a printer repair problem.  It’s a user error.

If your HP, Lexmark or Kyocera laser printer drawer is setup as legal size and you send a 8.5″ x 11″  (standard size paper) print job to it you will receive this error “size mis-match” or a message that says to load standard paper. The printer is acting correctly.  If thinks is should be getting a legal job sent to the paper drawer but instead you are sending a standard size paper job.  The repair of the printer is simple:  change the paper in the drawer to standard size. Now if you wanted to print legal and you think you are sending a legal size job and you get this message the Lexmark HP printer repair is still not needed.

Always check the properties for paper size when you get this message. You will get the HP printer repair error size mis-match if your properties of the file you are sending is incorrect. Each document you send to the Lexmark, Kyocera, HP or other laser printer maintains information from the last time it was printed.  If the last time you used legal paper when printing then unless you change the properties of the file with your computer it will think you are using legal size paper again. If you printer has standard paper and the computer says legal then you will get a size mis match error. The computer ALWAYS overrides the printers default configuration.

The MP tray is a little different. The MP tray can not tell the difference between legal or standard size paper.  If you say legal and it has standard 90% of the time you will get a paper jam! Why? Because it is expecting a long sheet of paper when it is printing and when it see the end of the page too soon it will give you a error. This is a simple HP repair maintenance problem resolution.

This simplifies the repair of HP Lexmark Kyocera printers.  Advanced Business Computers Inc in Miami Florida will help with your repair problem with one simple phone call 305 477-2320 or send them an email for additional help with your laser printer copier fax repairs and maintenance.

 

One of the more common problems is a light print or a vertical area of a page with light or no text on the printer copier.  Most printer copier image repair problems are a process of elimination.  All digital laser or led based printer copiers faxes use toner and developer that are either mixed in the copier printer or premixed in the toner cartridge. Knowing this fact is important when repairing copier printer scanner equipment.

If you need to repair printer image problems then with light areas then first determine if you have a toner cartridge that contains both toner and developer or if you have separate toner, developer and drum unit.  If you have an all in one toner cartridge then change the cartridge to see if the problem is resolved.  If changing the toner, developer drum all in one cartridge resolves the problem than you are either low on toner or there is a blockage in  the developer area of the cartridge.

If your printer copier has separate toner, developer and drum units then you need to look at the developer unit first and then the drum unit to repair the copier printer light image problem.  If you  are low in developer or the developed mag roller has a blockage then it will cause light or totally blank areas on your print.  When you repair of the copier printer image problem be careful not to touch the mag roller with your fingers which can cause skin oils to damage the roller and cause future clogs.  Now check if you are low of developer powder. Some copier printers do not require replacing the entire developer unit if you are low in developer. Instead you just need to buy the developer powder, put in the powder and adjust the machine. If you are not sure ask your copier printer repair technician.

If you copier printer is not low on developer look for blockage in the toner hopper or developer unit. Blockage will either cause toner and developer not to mix properly or not to be transferred to the drum unit. Another cause of light prints is the fuser assembly not applying enough pressure on the page to fully transfer the toner but this is a less likely cause than a developer problem.  Copier printer repair requires qualified technicians to resolve problems quickly.  This article is designed to give you and idea of the copier printer scanner repair process so when you speak to your certified printer copier repair tech you have a understanding of what they are telling you.
