Top 20 HP LaserJet 4730 MFP Printer - Page 6 Questions & Answers

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.

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.

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.

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

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.

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

Juliet. Most likely the scanner lamp, or scanner control unit assembly is defective. If you're technically savvy, you could remove the scan glass and lube the shaft that the scan lamp assy slides on. Sometimes that will fix it. Otherwise, the whole top scan unit will need replacing. That could cost over $300 for the replacement.

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.

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

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

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...)

hey, Its a scanner error - often these can be fixed. The poster above forgot you have 2 scanners. Your error refers to the laser/scanner which is the unit that writes the information to the drum of the toner cartridge for printing. A bit different and a little harder to get to. The laser/scanner is the black box that sits above the toner cartridge on the frame and you have to remove the scanner/adf unit to get to it. The service manual has directions. When you remove the laser/scanner it you open the black box carefully you will see a chrome motor wheel towards the back that spins. Usually the shaft of that motor has become to tight with debris or other material and can not get up to speed. Sometimes there is a small clip that secures the motor in place and other times you can just lift up the chrome piece and it comes out. In either case you need to place one tiny drop of synthetic oil down the shaft of that motor, put the chrome piece back on, spin it a few times to make sure it is smooth and then put everything back together. It should then work. If not then the laser/scanner needs to be replaced. The first thing you will want to do is check the flat ribbon cable on the left side of the printer that plugs into the board. It will be the thinner cable. This scanner error - often these can be fixed. Click here the lick below to Download SmartPCFixer for Free to repair. Fix PC Errors Optimize Your PC
