Error light flashing when printer is taken off line

When doing a cheque run we need to make vertical adjustmentts to the print lineup and usually do this by taking the printer off line whilst printing, feeding the paper through then turning on line again. It has never caused a problem in the past but now as soon as we take it off line, the error light continually flashes and we can't restart the print.

Yellow light keeps flashing underneath triangle- Error code 6480. Please advise what this means? many thanks

There is a thin (1/4"wide) plastic strip running across the width in front of and below the drive belt. This is part of the optical encoder that tells the print-head where it is. If you look closely, there are fine black vertical lines on this strip. If the strip gets a piece of crud on it, you get an error during the start-up sequence. Gently clean this strip with a damp lint-free tissue. This also will fix a gap in the printing running lengthwise (not across the page like a clogged head).

Light Printing on a Zebra 2844

You will know when the printhead is starting to wear out by seeing white vertical lines. The line is a "void" area caused by an element/elements that are worn away - no image is being produced. Darkness is usually controlled by the printer driver and/or the label software being used.

Hp 4550 vertical line down center of page

From the service manual:

Vertical lines or streaks
 Check for a leak where light might be entering the printer.
 Check for circumferential scars on the photosensitive drum. If scars are present, replace the
drum cartridge if the line goes through all colors.
 Check for circumferential scars on the upper fusing roller. If scars are present, replace the upper
fusing roller if the line goes through all colors.
 Remove the imaging drum and inspect main charger or imaging drum for a contaminant, such as
a fiber, if the line goes through all colors.
CAUTION Do not expose the imaging drum to light for more than 15 seconds. The drum is light sensitive, and
exposure to light can cause permanent damage.
Vertical black lines
 The toner cartridge is defective.
 The toner cartridge is not seated properly.
 The fuser entrance is dirty.
 The fuser has scratches on it.
 This might be a repetitive defect. If so, the lines will repeat at a consistent interval down the page.
 The printer needs to be cleaned.
 There is a problem in the heating element.
Vertical white lines
 If white lines or streaks appear only in the black areas of the printed media, print several
configuration pages to clear the anomaly. If this does not clear the problem, check the sleeve
surface to confirm the defect, then replace the black toner cartridge.
 If white lines appear only in a particular color, try printing several configuration pages to clear the
error. If the error does not clear, check the sleeve surface to confirm the defect, then replace the
defective toner cartridge.
 There is a lack of toner or the toner cartridge is faulty.
 There is dirt in the laser path.
 The fuser is defective.
 A mirror in the laser scanner is dirty.

Light keeps flashing red,amber, green

If you turn off the printer and turn it back on, do you get any noises, ie motor noises, or does it instantly go to all lights flashing?
If you get no noises this usually indicates a board fault and you should look for a new printer.
