HP Color LaserJet 2550L User Manual

							Selecting an output location
The printer comes with the top output bin and a rear output door for printing to a straight-
through paper path. Print jobs emerge from the top output bin when the rear output door is
closed. Print jobs emerge from the back of the printer when the rear output door is open.
●Use the top output bin when printing most jobs, including jobs on average-weight paper
and letterhead, and transparencies. The top output bin can hold up to 125 sheets.
Prevent more than 125 sheets from accumulating in the top output bin, or jams can occur.
●Use the rear output door (straight-through paper path) if problems occur when printing to
the top output bin. Remove each sheet as it exits the printer.

							Printing on special media
Printing speeds might be automatically reduced when printing on any special print media.
Printing on envelopes
●Load envelopes into tray 1 only.
●Do not load more than 10 envelopes into tray 1.
●
The weight of the envelope paper should not exceed 90 g/m
2 (24 lb).
●Make sure that envelopes are not damaged and are not stuck together.
●Never use envelopes that have clasps, snaps, windows, coated linings, self-stick
adhesives, or other synthetic materials.
●If you are using a non-standard size of envelope, select the appropriate envelope as the
Type.
CAUTION
Failure to follow the guidelines above can result in jams.
For more information, see 
Print-media specifications.
To print on envelopes
1. Open tray 1 and slide out the extender fully. If tray 1 is already open, remove any paper
or other print media from it.
2. On the back of the printer, lower the rear output door to prevent the envelopes from
curling.

							3. Slide the side-width guides in tray 1 outward until they are slightly wider than the
envelopes.
4. Place the stack of envelopes into the tray with the side to be printed on facing up and
with the short edge leading into the printer. The stamp end must enter the printer first.
NoteIf the envelope has a flap on a short edge, this edge must enter the printer first.
5. Slide the side-width guides inward until they lightly touch the stack without bending it.
The stack should be centered between the guides and must be under the tabs on the
guides.
6. Select the envelope you are using as the Size (Windows) or the Paper Source
(Macintosh) in the Print dialog box or the printer driver.
Printing on labels
Follow these guidelines for using labels. See Print-media specifications for more details.
ENWWPrinting on special media43
 
						

							CAUTIONTo avoid damaging the printer, use only labels that are recommended for laser printers. To
prevent serious jams, always use tray 1 to print on labels and always use the straight-
through paper path. Never print on the same sheet of labels more than once or print on a
partial sheet of labels.
●Avoid labels that are separating from the backing sheet or are wrinkled or damaged in
any way.
●Place labels only in tray 1 with the side to be printed on facing up and the top, short
edge in first.
●Select Labels as the Type (Windows) or the Paper Source (Macintosh) from the Print
dialog box or the printer driver.
●Remove label sheets as they print from the straight-through paper path to prevent them
from sticking together.
●If a sheet of labels jams in the printer, see 
Clearing jams.
Printing on transparencies
The printer supports printing on color transparencies. See Transparencies for more details.
44Chapter 3 Printing tasksENWW
 
						

							CAUTIONTo avoid damaging the printer, use only transparencies that are recommended for laser
printers. To prevent serious jams, always use tray 1 to print transparencies.
●Load transparencies into tray 1 only.
●Select Transparencies as the Type (Windows) or the Paper Source (Macintosh) in the
Print dialog box or the printer driver.
●Use the top output bin to reduce curling. (This rule is for transparencies only. For other
special print media, use the straight-through paper path to reduce curling.)
●To prevent transparencies from sticking together, remove each one from the top output
bin as it prints.
●Place transparencies on a flat surface after removing them from the printer.
Printing on glossy paper
This printer supports printing on glossy paper. Follow these guidelines when printing on
glossy paper. See 
Print-media specifications for more information.
●Load glossy paper into Tray 1 only.
●Select Glossy or Heavy Glossy as the Type (Windows) or the Paper Source
(Macintosh) in the Print dialog box or the printer driver. Select Glossy for media weights
up to 120 g/m
2 (32 lb bond). Select Heavy Glossy for media weights up to 163 g/m2 (43
lb bond).

							Printing on HP LaserJet Tough paper
When printing on HP LaserJet Tough paper, follow these guidelines:
●Handle HP LaserJet Tough paper by the edges. Oil from you fingers that is deposited on
HP LaserJet Tough paper can cause print-quality problems.
●Use only HP LaserJet Tough paper with this printer. HP products are designed to work
together for optimum printing results.
●In either the software program or the printer driver, select Tough Paper as the media
type, or print from a tray that is configured for HP LaserJet Tough paper.
CAUTION
Transparent print media that is not designed for LaserJet printing will melt in the printer, and
will damage the printer.
Printing on custom-sized print media or cardstock
Postcards, 3-by-5-inch (index) cards, and other custom-sized print media can be printed on
from tray 1. The minimum size is 76 by 127 mm (3 by 5 inches) and the maximum size is
216 by 356 mm (8.5 by 14 inches).
●Always insert the short edge first into tray 1. To print in landscape mode, make this
selection through your program. Inserting the media long-edge-first might cause a jam.
●In your program, set margins at least 6.4 mm (0.25 inch) away from the edges of the
print media.
●Select the custom media that you are using as the Type in the printer driver and set the
correct Size.
●Lower the rear output door to use the straight-through paper path and reduce curl.
See Print-media specifications for more information.

							Printing on letterhead or preprinted forms
This section shows how to orient letterhead or preprinted forms when you are printing only
on one side. For duplex (two-sided printing) orientation, see 
Printing on both sides
(duplexing manually).
●Orient paper as shown in the following figures.
●If the print media is heavy, lower the rear output door to reduce curl.
●Avoid using raised or embossed letterhead.
●Avoid using letterhead that is printed with low-temperature inks, such as those used in
some types of thermography.
●The printer uses heat and pressure to fuse toner to the print media. Make sure that any
colored paper or preprinted forms use inks that are compatible with this fusing
temperature (210° C or 410° F for 0.1 second).
ENWWPrinting on special media47
 
						

							Printing on both sides (duplexing manually)
To print on both sides of the paper, you have to return to the printer and reinsert the paper
manually after the first side has printed.
CAUTION
Do not print on both sides of labels or transparencies. Damage to the printer and jams might
result.
Note
The PS printer driver does not support manual duplexing. For Mac OS 9.x you must perform
a custom driver installation and select the plug-in for manual duplexing. Mac OS X does not
support manual duplexing.
To duplex manually
1. Insert enough paper into one of the trays to accommodate the print job. If you are
loading special paper such as letterhead, load it in one of these ways.
●For tray 1, load the letterhead paper with the front side down, and the bottom edge
leading into the printer first.
●For optional tray 2 and optional tray 3, load the letterhead paper with the front side
up, and the top edge toward the back of the tray.

							Canceling a print job
A print job can be canceled from a program, from a print queue, or from the  (CANCEL JOB)
button on the printer.
●If the printer has not started printing, first try to cancel the job within the program that
sent the print job.
●If the print job is waiting in a print queue or print spooler such as the Printers folder in
Windows (Printers or faxes in Windows 2000 or Windows XP) or Print Monitor or
Print Center Queue in Mac OS, try to delete the job from there next.
●
If the print job is already printing, press 
 (CANCEL JOB) on the printer. The printer
finishes printing any pages that are already moving through the printer and deletes the
remainder of the print job.
●
Pressing 
 (CANCEL JOB) cancels only the current job in the printer. If more than one
print job is in printer memory, you must press 
 (CANCEL JOB) once for each job after the
job starts printing.
If the Printer Status lights continue to cycle after a job has been canceled, the computer is
still sending the job to the printer. Either delete the job from the print queue or wait until the
computer finishes sending data.
