Printer won't stop printing garbage

HP Deskjet 812C will not stop printing random letters and symbols. I have tried cancelling all print jobs and that does not work.

    I too have this problem. And I know what it causes it. Anytime you interfere physically with the printing process, the HP 812C goes haywire. Anything that is in the printing buffer becomes garbage, filled with a lot of page breaks, I mean a lot. Canceling the print job doesn't help. Pulling the damn plug doesn't help. You just have to keep feeding paper to the damn thing until all the garbage is out of its buffer. Sometimes can take twenty or thirty minutes and a lot of paper. Not to mention using all that ink. It is a huge waste of resources. Never been able to find a way to clear the buffer. Good luck...they are tempermental creatures.

I had the same problem. I fixed it by using an elevated command prompt to clear the print queue, turned off the printer, removed all the paper from the printer, restarted the printer, at this point let it try to print - it discovers it is out of paper and cancels the print job, clearing the buffer. I paper back in the printer and pushed the paper button - it printed out one line of random characters, and then resumed normal operations.

I had the same problem hooking my old HP Deskjet 812C to a computer running Windows XP with a parallel printer cable. I tried changing the cable to a new printer cable and the printer was immediately detected and installed on reboot. I think my old printer cable might not have been bi-directional.

Try and re-install your printer drivers...first remove the drivers and delete the printer...then re-install.

Prinnter not printing but showing 'put custom in manual tray'


There is still a print job in the queue. Place a sheet so it prints or kill the job.


Open Printers and Faxes. Open printer. Highlight jobs and Right click > Cancel, or Documents > Cancel.
For those stubborn jobs, Right click My Computer > Manage. Choose Services and Applications > Services > Print Spooler. Right click and stop. Then start. This may have to be done from the Print Server if it's network printer. Contact IT to kill.

Laser printer makes light clicking noise when idle


When idle is potentially the fuser unit, after heating and cooling. However the print quality issue associated with the clicking sound could indicate an electrical issue. The HVPS maybe faulty causing the print quality issue (due to dependant parts) and the electrical click. In any case I would recommend calling Brother and finding the nearest authorised service agent.

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.

Samsung kicked out hp 3in 1 printer already installed


Don't have your HP designated as the default printer (if possible)when you hook up the Samsung. When the Samsung is hooked up it sees the HP is the default printer. Well it can't have that, they discard the HP drivers. What does Samsung care about HP drivers theres only one printer port setup and thats the USB port you have them sharing. So yes you need to get a second cable. Tim
