With all the companies going out of busy its become a free for all in the user copier printer scanner fax markets.  We consistently get calls from companies who have purchased used copier printers machine from companies going out of business or at auctions that lasted a few days and then started to haev problems.  When purchasing a used or reconditioned copier printer scanner fax whether Canon, Ricoh, Sharp, Kyocera or other brand you need to thoroughly test the unit.   Better yet hire a certified service technician to check ti out first before parting with your hard earned money.

One of the more common problems we are starting to see lately is the system rest of the factory configured calibrations and even the serial numbers. on many brands of printer copier scanners fax MFD machines a service technician can reset the factory ONLY calibrations settings. These settings control the laser strength, density calibration and even house the serial numbers.  Once these are reset they can not be recovered or properly recalibrate because these calibration settings were done at the time of the manufacturer of the copier printer using specialized equipment not available in the field. can you tell if the settings haev been changed?  Yes and not

If you print the configuration or service log history you may notice an entry stating that the system was reset. Or if you print the used reconditioned copier printer configuration or service page and notice no serial number then you know somebody tampered with the counters, and factory only settings.  Purchasing a used copier printer fax is just like purchasing a used car. You want to know the true past history and usage. It’s better to have a service technician review the copier printer scanner used or refurbished equipment before you buy to prevent costly repair maintenance after a few days or weeks after purchase.

What can go wrong when the settings are reset? Plenty – first image quality when you replace the developer or drum unit. Second – lose of functionality of the unit that requires activation codes to use the fax, scanner or printer features.  Inability to get a maintenance agreement because the serial number and history is wiped out.  Used refurbished printer copier scanner office equipment will greatly reduce your overall cost but selecting one that was reset can be a costly mistake.

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.  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.

Your HP laser printer requires periodic maintenance. This maintenance includes repairing the fuser assembly of the printer. The fuser is a common problem that causes laser printer paper jam repair and toner smearing problems. The fuser error code on the HP laser printer is 50.x where is a number between 1..5.

Hewlett Packard fusers assemblies are replaced every 80,000 to 2000,000 pages depending upon on the laser HP printer model.

The first step in repairing a fuser error is to turn off the HP printer and let the laserjet cool down for at least 30 minutes.  Unplug the power cord and then make sure the fuser assembly is cool. Remember the fuser assembly gets very hot which can causes serious burns – far warning. If you are not sure of your abilities get a certified HP repair technicians to replace the fuser causing the printer error

Now open the back of the printer (you may need to remove covers and/or exit trays). Remove the screws holding the printer repair part you are replacing (fuser) and slide out the unit. Slide in the replacement fuser assembly and reassemble the back of the HP laserjet printer you are repairing.

Some clients do not want to put in the whole assembly. The fuser assembly of an HP printer consists of several parts. We do not recommend that you rebuild the unit unless you have previous fuser assembly rebuilding experience. You need to replace the roller, bearings, pick fingers, heat roller, Thermister, thermostat, and have good mechanical abilities.  Contact an authorized HP printer repair service center instead
