Doc feeder jam error on HP laserjet M1522nf continuesly also due to that i am unable to scan and also its showing that "Device is busy try again later"

Go to LINK.

this error can be caused by a paper jam, or a little piece of paper in the toner area, Take the cartridge out and use a flashlight to check in the sides looking for paper. Other reason is that sometimes the sensor that detect the toner is out of place and in that case you can try to power cycle with the toner out before you install it again. Good luck

The jam it's talking about is in the feeder on top. Check for stuck paper, or a sensor stuck down, in the feeder area on top

Have a good day

Based on the assumption it's mechanically ok, check the cable connection between the document feeder and the base, if damaged or worked look it can cause errors. If it is a sensor error, check for a small bit of paper or even a staple from a prior jam.

the Error is "the software had trouble scanning or was cancelled" in HP printer 2727 MFP please advice

HP LaserJet 3030 All-In-One Printer
Doc. feeder jam, after paper removed completely

Copy function was not working, says "device is busy". Message appeared on the printer screen is:"scanner error 5, turn off then on". This was done several times and message still appeared. I called 866-625-1176 and was connected with HP Technical Support and after 20 - 25 minutes of diagnostics, the technician informed me that they were sending me a new printer at no charge. I assume this meant that HP is aware of the defect and has no solution other than to replace it. The printer was only 6 months old.

I have a Laser Jet 3050..when I try to load a oaoer to copy or fax, paper does not move...just gears moving but paper is not being pick up...any solutions?

there is no paper in document feeder
