Service error 6C00 - at my wits end

I have had this printer for just more than a year. A couple of months ago, occasionally when I would print, it would come up with service error 6C00 and wouldn't print. I checked the printer, opened everything, checked for jams, pressed ok and it worked. I'm at the point now where I have to follow those steps in order to get the printer to work. Now, I can't even get it to work - just keeps coming up with the same error and I can't seem to clear it out. I've also turned the power off and unplugged it. Has anyone had any problems with this? Any solutions other than taking it to a service center or buying a new printer? Thanks!

Can the ink dry up. installed printer ink a couple of months ago but will not print now. printer prints blank pages.


yes ink can dry up.. big chance your ink have dried up, since you've installed them couple of months ago.. there's a possibility that the ink may have not dried up but the print head may clogged.. you can try running some maintenance like clean cartridge or print head test using Dell All inOne Solution center..
Hope this helps..

Most likely the the ink carts are low or you have a one defective cart. Do steps in sequence
1. Reseat carts 2. Reset the printer. 3. Rpl carts one at a time till you find the defective one.

Service required error

Ok.. aside from the fact that you've posted under the R300 Epson model thread you're still in luck.

The CX6600 has been documented (by me admittedly) with a complete guide to fitting an external tank and resetting the waste ink counter in the printer.

Just to note: This is a commercial site but the information provided is generic and will help you fix the problem.

Paper jam error after last page prints

Hi Natoli3,
This could be a mis-match of paper sizes. Example, computer could be sending an A4 page to the printer. The paper size in the could be set to Letter. Ensure the 4 paper sizes match, in the computer - the document and printer driver; in the printer (change in control panel) and paper tray (adjust the physical side and length).

Hi wolst, try updating your printer drivers:

Create a new folder on your desktop and name it newhpdrivers(substitute your manufacturer in new name). Un-intall printer and printer software completely. Go to manufacturers website and navigate to their drivers/downloads or support menu. Select your model, choose the relevant software and download to the new folder you created on your desktop. Power down your computer. Reconnect the printer to the computer and turn printer on. Power on pc. Windows will detect new hardware and ask if you have the manufacturers install cd or a location to check for install files. Direct the wizard to your new software, follow the rest of the setup instructions and your done
