Pink "bands"on prints from my R1800-even after multiple cleanings

hi. the printhead may be clogged. perform a deep cleaning in printer properties

try to change the color ink. horizontal banding (the pink or other color lines appearing means horizontal banding) when there is a problem on one of the heating element of the printer head. since almost all canon printers have head built in the inks, replacing the faulty ink will solve the problem. if not then the controller of printhead on the carriage and mainboard needs to be checked.

I just had the same problem -- go to epson.com and look under drivers and support. Select the R1800 and go to FAQS, there it will tell you how to resolve a driver issue that can cause this.
Good Luck!

I've had the same problem, and finally after hours of frustration, got Canon to provide a new PrintHead at no charge

If nozzle Check is OK Try Reinstalling the Driver.

Not easy to tell. Epson claims a 100 years for some ink types under certain conditions. Nobody would be able to live for such a long time. Some researchers SIMULATE to get the aging process faster but I guess we have to leave Epson's claim a few generations after us to deliver the verdict. For now the jury just must wait. I have some prints done 8 years and counting.

Is the R1800 the only printer that you have on ythis mac?

If it is make sure it is directly connected to your mac via a USB or Firewire cable.

Trash epson folder from Mac HD-Library- Printers
Delete Epson printer utility from Mac HD- Application folder( if you have both delete both icon.

Under prnter setup utility delete the r1800 printer

Go to finder click on file the find, type com.apple.print, if it find anything drag it all on the trash, it will not disappear from the window ( the prefs and . cache files)

download the latest driver for your r1800 from epson website
epson12113.dmg - 10.3MB - posted on 12/20/

then reinstall it, after reinstalling try to readd th printer and make sure under print using it will say Epson SPR1800 series. If you see guten print/ that is a third party driver. dont use the gutenprint. then try to print, update me for the outcome

Had the same problem - but the print head is actually easy to remove.

1) Remove ink cartridges
2) Remove 3 Phillips head screws at the bottom of the cartridge housing. (looking down from the printer front - top left, bottom left, top right).
3) There are 2 small plastic tabs on a plastic bracket that secure the flex cable on the right hand side of the cartridge housing. Gently release the tabs with a small flat head screw driver.
4) Lift the print head straight up (don't pull on the flex).

There may be a release for the flex to separate from the print head. But I did not see one. Instead I poured 1/4" of Windex in the bottom of a small plastic container and soaked my print head for about 15 minutes (occasionally agitating).

Then put back in reverse order - be sure to seat the flex in the guide (top-back-right) of the cartridge housing before screwing down. Then run a cleaning or two to flush the cleaning fluid out of the print head. (I have a waste ink tank installed so I am not worried about dumping excessive ink into the waste sponges).

The differences was remarkable - though there was still slight banding - maybe should have soaked longer (1 hr perhaps?) - I may repeat if it remains an issue.

Additionally there were large solid deposits on the left side of the print head which were responsible for scraping heavier weight photo paper. These dissolved in the Windex too.

Replace the print head, and all should be just fine.

Hi Tom, Have you downloaded the latest driver from the Epson web site. Also make sure the output tray is in the correct position and that you are using the correct paper. You can use the following media with this feature: Matte Paper - Heavyweight A3+, A3, A4 Premium Glossy Photo Paper A3+, A3, A4, 10 x 15 cm (4 x 6 in.), 329 mm x 10 m, 210 mm x 10 m (Roll paper) Premium Semigloss Photo Paper A3+, A3, A4, 329 mm x 10 m, 210 mm x 10 m, 100 mm x 8 m (Roll paper) Archival Matte Paper A3+, A3, A4 Watercolor Paper-Radiant White A3+ Velvet Fine Art Paper A3+ Ensure the output tray is in the correct position as if the tray is too low and the paper "falls" down into the tray the weight of the paper could pull the last few millimeters of paper out of the exit rollers, causing the band.
