media
always make sure that you are using the appropriate media for your image and that it is consistent with your software application. to ensure color accuracy and print-quality performance of the printer, use only media types that have been certified for your printer. use of non-hp media or hp media not certified for your printer may significantly reduce the color and print quality of your images. for details of hp media, see physical characteristics of media types.
handling your media
· handle film and glossy media by the edges or wear cotton gloves. skin oils can be transferred to the media leaving finger print marks.
· although the ink systems supplied with this printer have good light fastness, colors will eventually fade or change if exposed to sunlight over a long period of time.
· rewrap partially used rolls if they are not being used and do not stack rolls.
· always keep unused rolls wrapped in the plastic wrap to prevent discoloration.
· keep the media tightly wound on the roll throughout the loading and unloading procedures. if the media starts to unwind, it can become difficult to handle.
clearing a media jam
the "switch power off" message is usually shown when there is a media jam.
the printer must be cleared before the printer can operate again. there are two types of media jam:
· a jam that prevents the carriage from moving from one side of the printer to the other. this is called printhead path jam. see check printhead path procedure.
· a jam that prevents the media from advancing into the printer correctly. this is called a media path jam. see check media path.

check printhead path
1. switch the printer off at the rear of the printer and open the window.
2. look in the area where the printer was printing at the time of the jam, this is where the media is most likely to be jammed.
3. lift the media load lever.
4. carefully remove any of the jammed media which you can lift up and out from the top of the printer.
5. carefully pull the rest of the roll or sheet down and out of the printer.
6. if you are using a roll of media trim the media with a knife as shown on trimming the media.
7. reload the media see loading roll media.
8. switch the printer on.
9. if there is some media left behind in the media path, loading paper can become difficult. this can be cleared by loading a rigid paper type through the printer media path.
10. if you have image quality problems after a paper jam, this could indicate that the printheads have been moved from their correct position in the carriage. to correct this perform the "aligning the printheads" procedure.
check media path
1. switch the printer off at the rear of the printer.
2. check that the roll of media has not almost finished and is stuck to the empty cardboard core.
3. load a new roll.

if after performing all of these procedures the frontpanel displays the "switch power off" message again, make a note of the message with the error code and contact hp.
ink marks on the media
media extensions
printed surface smearing roll
as the media is printed and the image is coming out from the printer, the natural curl of the media causes it to rub against the roll of media installed in the printer.
this causes image smearing.
in addition to this, if the out-coming media sticks against the roll, because the ink is not dry or because of static (some polyester films get electrostatically charged) it could cause the media to re-feed into the printer.
make sure that the media extensions are installed onto the printer (shown right). the extensions don't reduce the way media is charged, but the increased distance between the roll and the out-coming media, reduces the probability of having both surfaces being attracted (and smears).

warped lines on media
· the media itself may be warped. this can happen if it has been used or stored in an extreme environment. for all environmental specifications, see environmental specifications.
blurred lines (ink "bleeds" from lines)
· perhaps you have adjusted the drying time in the front-panel menu to speed up the printer output. set "drying time" to "automatic".
for details of drying time adjustments, see drying time settings.
marks or scratches on glossy paper
glossy paper may be extremely sensitive to the bin or anything that it comes into contact with directly after printing. this will depend on the amount of ink printed and the environmental conditions that are present at the time of printing. avoid any contact with the paper and handle the print with care until quite some time has elapsed.
marks or scratches on double-sided media
if you are using double-sided media and there are marks and scratches evident on the media, it may mean the platen needs cleaning. perform the procedures detailed in cleaning the platen.
smears or scratching on the image
this problem can appear on paper-based coated media if a lot of ink was printed. the media absorbs the ink quickly and expands. as the printheads move over the paper, the printheads and the paper come into contact with each other and the printed image is smeared.
1. press the cancel key on the front-panel; if you continue to print, the paper may damage the printheads.
2. cancel the print job from your computer application.
in order to obtain better results perform the following:
· use hp recommended media. if the image you are printing has intense color, try using hp heavyweight coated paper economy through the front-panel.
· use extended margins see adjusting margins, or try to increase the print margins by relocating the image in the page from your software applications.
· ensure that the media extensions are installed on the printer
· if you are using "media saving options" from the advanced section of the hp- gl/2 driver, try disabling one or both the options "auto rotate" and "inked area".
· use the take up reel if you have one installed.
if the above fails to solve the problem of smears and scratching, change the media you are using to a nonpaper based media such as glossy film.
the media cannot be loaded successfully
roll media
· the roll may be loaded the wrong way. the paper should load over the roll toward you.
· the media may be crumpled or warped or may have irregular edges.
· the paper may be loaded at an angle.
the right-hand edge must be aligned with the edges of the roll of media.
· ensure that the paper is wound tightly on the roll.
· check that the paper is correctly loaded onto the spindle.
sheet media
· it must be loaded with the right-hand edge against the blue perforated line on the printer.
· align the sheet media against the trailing edge coming out of the printer.
· the media may be crumpled or warped or may have irregular edges.
· if you are using hand-cut media, the edges may not form a right-angle or they may be rough. do not use hand-cut media. use only purchased sheet media.
prints do not stack properly in the media bin
· the printer may be too close to the end of the roll.
the natural curl near the end of the roll can cause stacking problems. load a new roll or remove prints manually as they are completed.
· if you are mixing prints or nesting sets of several different sizes, you may have stacking problems because of the different sizes of media in the bin.
