Hp laserjet m1522f error 5 turn off and on


Hi, Error 5 is a Scanner error. When turning the printer on, have the lid up so you can watch the scanner movement. Does it move smoothly? It should go through a warm up and you should be able to watch the scanner movement. If there is a problem with the scanner, there isn't a lot you could do except. The service manual says the scanner assembly should be replaced. If it was my printer, I would try to take a closer look at the scanner assembly and check to see if the scanner unit is bound up somewhere, or maybe a drop of 3 in 1 oil on the scanner rails. Let us know what happens.
thanks

Why does canon MP258 printer with scanner can't scan japanese yen paper bill amount 10,000. I tried it over 10 times but it stops,. And when i tried US paper bill, it works well. I need some explanation...


When you scan with any scanner it utilised the software with "Optical Character Recognition functions, usually abbreviated to OCR -> OCR is a field of research in pattern recognition, artificial intelligence and computer vision." to scan and record the scanned object, sometimes it does not or cannot recognise certain symbols or characters because of man made software & hardware have its limitations too.

Hope it helps.
