HP DeskJet 1200C, 1200C/PS, 1600C, 1600CM, and 1600CN Printers - Problems Printing Transparencies / Letterhead
Why does the Check Paper light flash on the HP DeskJet 1200C/1600C printers when attempting to print on transparency film or pre-printed letterhead paper. Printing on plain white paper works fine.
The HP DeskJet 1200C/1600C printers use an optical paper sensor to determine the position of the paper. The sensor not being able to identify the position of the paper inside the printer usually causes transparency film and letterhead printing problems. Read the appropriate items below to identify the cause.
HP Premium Transparency Film has a white strip at the top of each sheet. The paper sensor uses this strip to determine if there is transparency film loaded.
When loading transparency film into the paper tray, insert the film with the white strip physically on top and on the end of the film that feeds into the printer first.
If the transparency film is put in backwards, or the film does not contain a white strip, the printer will not "see" the transparency film.
The white strip may be removed from the transparency after the transparency has been printed.
If pre-printed letterhead contains a dark solid area, it is possible that the optical sensor may not "see" the paper (the light is absorbed by the dark color). To correct the problem, try changing the location of the letterhead on the page. The paper sensor looks approximately one inch in from the left-hand side of the paper.
note:Dark colored paper may also cause similar types of problems where the printer cannot "see" the paper. Try lighter colored paper to correct the problem.
