Since exposed meter probes could deliver a fatal electric shock this should be left for an experienced technician if you have the slightest doubt about your own abilities. While this error does not occur very often in these models there are a few things you can try before making the choice to replace the fuser. If the error persists, replace the ECU. 8. If you see this happening on large print runs, break up the large print jobs into smaller jobs allowing the machine to cool down periodically. have a peek here
It is possible that the thermistor contacts were tarnished - and you might find a label or other foreign object stuck around the fuser sleeve preventing it radiating heat properly. Below is what the service manual says so if everything fails then unfortunately the fuser will need to be replaced. What Could Go Wrong? The DC controller is told what temperature to reach by commands from the control panel, or from the formatter (which gets them over the network from the driver in the user's http://printerrepairsupport.com/50-3-fuser-error-hp-p4015-p4015-p4515/
You should allow several inches on all sides of the unit so the exhaust fans inside can properly disperse the heat generated inside. There is no harm in it. A bit more information on toner behaviour is available under the CC364A cartridge heading. An error message will be a help here as running the fuser too hot will shorten it's life.
The fuser may not be to blame. Engine Test Location on the HP P3005 Laserjet Printer 50.2 Fuser Error Warm up issue in the HP Laserjet P3015 PrinterParts and Supplies StoreBrother Parts / Supplies Canon Parts / Supplies Also the environment or having the main cooling fan blocked can result in high temperature problems inside the machine. If the mains voltage is 10 percent higher than it nominally ought to be, then current goes up 10 percent as well and so the power output of the fuser is
The fuser shouldn't be run too hot - it is bad for the pressure roller rubber and the bearings if nothing else so if it does go to error that may It is possible that firmware might be confused by particular settings. It would need a supply rated at 3 kilowatts or more (about 4KVA) to guarantee a good supply to most laser printers. (The fuser is a resistive load, but it has http://printerrepairsupport.com/50-3-fuser-error-on-the-hp-p3015/ If you do need to purchase a new fuser check out the link below.
The heaters are quite powerful; in action the printers draw just under a kilowatt of power and almost all of that goes towards fusing. Wrong settings. If the message persists, replace the whole MFP. It is fairly easy to test a thermistor- they are simply resistances that vary with temperature.
If so: It is going to be difficult to diagnose, the power supply is deep inside the machine and not easy to work on because it deals with mains power and http://h30434.www3.hp.com/t5/LaserJet-Printing/error-50-3/td-p/4902255 These machines have operating temperature guide lines. The DC controller and environment sensor thermistor could be implicated. the message appear on the screen is error 50.3 and it says the fuser error then turn off and on again.very appreciated if any one can help me how to reset
Generally a higher setting will work better on heavier media like letterheads and envelopes - at the possible cost of a shorter life for the fuser. http://xhpcreations.com/fuser-error/50-0-fuser-error.html DO NOT merely turn the printer off and on again, there is a risk that a second dose of power will push the fuser to the point where the fuser cutout It is also difficult to fix without dismantling the fuser. Pull the fuser out of the back of the product.
Push up on the link arm to release it. This content is provided “AS IS” and is subject to change or removal at any time. Thank you! Register · Log In HP Support Forum Home > Printers > LaserJet > HP Laserjet 4250. http://xhpcreations.com/fuser-error/fuser-error-50-2.html Before you start replacing the fusing unit, RM1-4554-000CN, for the 50.3 fuser error it's best to try a few things that might resolve the problem without replacement.
Release one tab. 7. This one did a few years service in a shipyard and still functioned but it is easy to see how they could get completely clogged. You may need to test the mains power (line voltage). Four fans cool the machine.
Hopefully if you do see this error on your machine the tips and instructions above will help you resolve the 50.3 fuser error in a timely manner. New "High Voltage Power Supplies" from HP are expensive - although we can probably source "refurbs" (ie clean working pulls) from decommissioned machines. Bad frequency or power factor. this contact form If the message persists, replace the DC controller. 4.
Thanks again, for all the support. Other things that can cause the 50.3 fuser error are sitting the fuser temperature to High 2 and letting it run for a long period of time. Slide the right-rear cover toward the inside of the product to release it. 2. However the fuser should be moving and at temperature before the print media arrives so if the film is not carrying heat away presumably the 50.3 error could happen.
Amazon, the Amazon logo, Endless, and the Endless logo are trademarks of Amazon.com, Inc. Make sure all the fans are fairly clean and spin freely. The thermistor feeds temperature readings to the DC-Controller, a microprocessor responsible for print-engine actions in general. An excessive temperature might suggest a ventilation problem or fan failure.
If you must have printing protected by a UPS choose an inkjet, they don't have the high power demand of a fuser. 50.3 problems seem likely to be printers being fed Thermal Cutout. fixya The usual mixed bag of irrelevances with one mention of 50.3 and no solution. Quick Answers?
I've installed a maintenance repair kit but it doesn't seem to help with the jams. This allows the machine to totally cool down and by having the power unplugged lets the capacitors on the power supply to discharge. The toner is too hot, melts and sticks to the hot surface but the paper does manage to separate from the fuser. Bad Voltage.
Rotate the bottom of the cover away from the product, and then pull down on the cover to remove it.
