I hope this help. Hp Error Code 52 Service Errors 52 Scanner Printer Repair Fuser

When it start to peint blank pages ? after change toner ?

Power the printer off. Clear the print queue. Power printer back on. And print something easy, like an email. If that works, try printing the page that caused the error. If the 49 comes back, it's that document. Do what Deepak says.

You don't say specifically what printer you have (other than, presumably, an HP.) Is it always happening, or happening with specific print jobs? SOME HP printers will let you increase the amount of memory in them. Some have a setting in their driver that doesn't always match your installed memory - for instance, you may have 512 Mb but it thinks you only have 96 Mb. Short term, turn off the printer, wait, turn it back on, see if it will print.

you need to make sure that your printer is supported by TWIN , you can do that online.

Go to the Menu, Settings, network, Wi-Fi and under the menu navigate to see the SSID the printer is connected to. Regards, Mike

try with new cartrige

there is paper inside machine, look behind the fuser or inside duplex unit

If your printer won't print mirror image, try editing the document so that the mirror image appears on your screen. All printers will print that. I know MS Word has that capability. I hope that is of help.

LOOK IN YOUR MANUEL PAM, MAYBE YOUR OUT OF INK OR PAPER OR SOMETHING???

The last option under the system setup menu allows you to chose your language.

Delivery fan (fan #4). These are the fans that are at the top of the printer just over the top of the fuser. They might just be dirty or they might be defective.

If you have already removed the paper from the output bin, check the delivery flaps to make sure they move freely. If they do, remove the top and make sure the sensor flag isn't broken and that the sensor is connected and undamaged. If it is connected and undamaged, check connector J213 on the engine controller is seated correctly. If it is, you probably need to replace the output bin sensor. See attached video

Usually a failed formatter is the problem on smaller printers where they will not come to ready. Try disconnecting any data cables going from your computer to your printer and restart. If it comes to ready, you might have a corrupted print job stuck in the print spooler. If it does not come to ready when not connected to a computer then the formatter is done.

Try Engine test:turn on device open tray 1 and load paper (1 is the manual feeder)when you open tray 1 there's an engine-test switch, found it and press itEngine error are also cause too much resistance from toner, fusor or gears. Remove toner and check that it roll with your fingers on gears, and do same with fusor (could be very hot warning - should be hard move it but not too much) and with printer off and fusor removed check if you can move any gear manually (this can be harder but will help you determine if it's board error or resistance cause a gear problem).Any previous error happened with the printer can help to diagnose (jams, power off while printing...)

LaserJet 9050 MFP DISK NOT INITIALIZED

I would turn off the print and then turn on. This could be a main board issue.
