							3.Insert the new printhead into its correct slot in the carriage.
CAUTION:Insert the printhead slowly and vertically, straight down. It may be damaged if you
insert it too fast, or at an angle, or if you rotate it as you insert it.
4.Push down as indicated by the arrow shown below.
CAUTION:When installing the new printhead there may be some resistance, so you need to
press it down firmly but smoothly. You should hear a beep and see confirmation on the front-panel
display that the printhead has been inserted. If you have difficulty, see 
Cannot insert a printhead
on page 168.
5.Insert all other printheads that need to be installed, and close the carriage lid.

							6.Ensure the end of the blue handle catches the wire loop on the near side of the carriage.
7.Lower the handle to rest on the carriage cover.
When all the printheads have been inserted correctly and are accepted by the printer, the printer
beeps.
NOTE:If the printer does not beep when you insert the printhead and the Replace message
appears on the front-panel display, the printhead may need to be reinserted.
8.Close the window.
9.The front-panel display confirms that all printheads are correctly inserted. The printer starts
checking and preparing the printheads. The default routine process, when all printheads are
changed, takes 10 minutes. If the printer finds problems in preparing the printheads, it takes longer,
up to 45 minutes. For a single printhead insertion, the times vary between 2 and 40 minutes. After
all printheads are checked and prepared, the printhead realignment procedure runs automatically
if paper is loaded, see 
Align the printheads on page 172.

							Check printer status
You can check the current status of the printer in various ways:
●If you start the HP Printer Utility and select your printer, you see a page of information describing
the status of the printer and its paper and ink supplies.
●If you access the Embedded Web Server, you see information about the general status of the
printer. The Supplies page in the Main tab describes the status of the paper and ink supplies.
●The status screen of the printers front panel notifies you of any current problems affecting the
printer as a whole. You can also request information about:
◦
The currently loaded paper, with the View loaded paper key 
◦
The ink levels, with the View ink levels key 
◦
The ink cartridges, by selecting the Ink menu icon  and then Ink cartridge information
◦
The printheads, by selecting the Ink menu icon 
 and then Printhead information
Clean the exterior of the printer
Clean the outside of the printer and all other parts of the printer that you regularly touch as part of normal
operation with a damp sponge or a soft cloth and a mild household cleaner such as non-abrasive liquid
soap.
WARNING!To avoid an electric shock, make sure that the printer is turned off and unplugged before
you clean it. Do not let water get inside the printer.
CAUTION:Do not use abrasive cleaners on the printer.
Replace the cutter
The cutter may need to be replaced once or twice during the life of the printer, depending on the total
amount and thickness of paper used. The front panel advises when replacement is due. If you do not
replace the cutter immediately, the printer continues working normally, but the front panel continues to
remind you about the cutter.
To replace the cutter:
1.If there is paper loaded in the printer, unload it.
2.
At the front panel, select the Setup menu icon 
, then Resets > Reset cutter life counters.
3.After a brief pause, the printer turns itself off. The printhead carriage is parked on the right-hand
side of the printer, and the cutter on the left-hand side.
WARNING!There is a risk of electric shock if you attempt to replace the cutter with the printer
turned on.

							7.Unscrew and remove the cutter stop using the TORX PLUS screwdriver provided with the new
cutter. The screw is captive and will not fall out.
8.Remove the old cutter.
9.Take the new cutter from the maintenance kit and move the plunger at the top slowly back and
forth within its housing to check that it moves freely.

							10.Slide the new cutter into position on the cutter rail.
The two wheels on the bottom of the cutter should engage the central ridge on the cutter rail, and
the two bushing guides should fit into the groove in the upper part of the cutter rail.
Check that the cutter runs smoothly up and down the rail. You can leave it anywhere on the rail;
the printer will park it correctly later.
11.Fit the cutter stop onto the end of the cutter rail, holding it there with one hand while you tighten
the screw with the screwdriver in your other hand.

							12.Put the left end cover back on the printer, aligning the protrusions with the holes in the printer.
13.Close the ink cartridge cover.
14.At the front panel, turn the printer back on. The printer checks that the cutter has been correctly
installed. Look at the front panel and follow its instructions if there is any problem.
Maintain the ink cartridges
During the normal lifetime of a cartridge, no specific maintenance is required. However, in order to
maintain the best print quality, replace a cartridge when it reaches its expiration date. The printers front
panel notifies you when any cartridge reaches its expiration date.
You can also check a cartridges expiration date at any time: see 
Check printer status on page 126.
See also 
Handling ink cartridges and printheads on page 113.
Move or store the printer
If you need to move or store the printer, prepare it correctly to avoid possible damage to it. To prepare
the printer, follow the instructions below.
1.Do not remove the ink cartridges or printheads.
2.Make sure that no paper is loaded.
3.Make sure that the printer is idle.
4.Disconnect any cables connecting the printer to a network or a computer.

							If you need to leave the printer turned off for a long time, follow the additional steps below.
1.Turn off the power using the Power key on the front panel.
2.Also turn off the power switch at the rear of the printer.
3.Disconnect the printers power cable.
4.Before transporting the printer, secure the rear tray in the closed position with tape. Otherwise, the
tray could open and perhaps break and fall out of the printer.
CAUTION:If you turn the printer upside down, ink could escape into the printer and cause serious
damage.
When the printer is turned back on, it takes about three minutes to initialize itself and to check and
prepare the printheads. Preparing the printheads normally takes just over a minute. However, if the
printer has been off for a six weeks or more, preparing the printheads could take up to 45 minutes.
CAUTION:If the printer remains off for a long period of time, the printheads may become unusable.
In this case, you need to replace the printheads with new ones.
TIP:Because preparing and purging the printheads uses both time and ink, you are strongly
recommended to leave the printer always on or in sleep mode, whenever possible, to maintain the health
of the printheads. In both cases, the printer wakes up from time to time to maintain the printheads. Thus
you can avoid going through lengthy preparation processes before using your printer.
Update the firmware
The printers various functions are controlled by software that resides in the printer, otherwise known
as firmware.
From time to time firmware updates will be available from Hewlett-Packard. These updates increase the
printers functionality and enhance its features.
Firmware updates can be downloaded from the Internet and installed in your printer in the following
ways; you can choose whichever you find most convenient.
●Using the HP Printer Utility for Windows, select your printer, the Support tab and then Firmware
Update.
●Using the HP Printer Utility for Mac OS, select Support and then Firmware Update.
●Using your printers Embedded Web Server, select the Setup tab and then Firmware update.
In each case, follow the instructions on your screen to download the firmware file and store it on your
hard disk. Then select the downloaded file and click Update.
