Changing Inkjet Print Cartridges

The HP DeskJet 420 series printer takes any one of the following inkjet print cartridges at a time:

Tri-Color HP51625A (supplied with printer)

Large Black HP51626A (optional)

Black HP51626G (optional)

See your local HP dealer or office supply store to purchase replacement inkjet print cartridges.

1. Open the printer door.

2. Press the Change Cartridge button ( ) to

move the print cartridge holder to the middle position.

3. Remove the inkjet print cartridge by pulling it by its green top.

4. To install another inkjet print cartridge, follow steps 3 through 8 on page 3.

Using the Inkjet Print Cartridge Storage Container

You can use either the color inkjet print cartridge supplied with the printer (HP51625A), or either of the following black inkjet print cartridges, purchased separately: large black (HP51626A) or black (HP51626G). However, you can only use one of these inkjet print cartridges in the printer at one time.

Always store the inkjet print cartridge that is not currently being used in the storage container. The storage container protects the ink nozzles from damage and prevents the ink from drying out while the inkjet print cartridge is not in use. This prolongs the life of the inkjet print cartridge, protecting your investment.

Determine which inkjet cartridge you are storing:

• To store the black inkjet print cartridge, make sure the arrow on the top of the black inkjet print cartridge points toward the cartridge clip on the left of the storage container.

• To store the color inkjet print cartridge, make sure the arrow on the top of the color inkjet print cartridge points toward the cartridge clip at the back of the storage container.

2. When removing an inkjet print cartridge from the storage container, be sure that the cartridge clip is disengaged, then lift the print cartridge out of the storage container.

Printing in Color and Grayscale

The HP DeskJet 420 series printer is designed to print in color using the color inkjet print cartridge supplied with the printer.

When printing with the color inkjet print cartridge, the black that appears, called “composite black,” is a mixture of the cyan, yellow, and magenta inks. The darkness of the composite black depends on the intensity settings and the print quality mode selected through your printer software. (See page 5, “Finding the HP Printer Setup Box.”) Use the darkest intensity and the highest print quality available to produce the “blackest” composite black.

Use the black inkjet print cartridge for better black text, and faster, more economical printing. For printing documents with the black inkjet cartridge, remove the color cartridge from the printer, store it in the storage container and insert the optional black inkjet print cartridge in the printer. If you are not using a bi-directional printer cable, select the black inkjet print cartridge in the Setup tab of the printer software. (See page 5, “Finding the HP Printer Setup Box.”)

See your local HP dealer or office supply store to purchase one of these black inkjet print cartridges:

Large Black HP51626A (optional)

Black HP51626G (optional)

You can print grayscale drafts of your color documents with the black inkjet cartridge. Click Print in Grayscale in the printer software. (See page 5, “Finding the HP Printer Setup Box.”) Your color documents will print in shades of gray until you change the setting and the inkjet print cartridge.

Prolonged exposure to air may cause ink crust to form on the ink nozzles of the inkjet print cartridge. You can try to clear the crusted ink from the inkjet print cartridge, as follows:

Note: Ink may stain your hands or clothing.

1. Hold the inkjet print cartridge by its green

top. Dip a clean cotton swab into distilled water and squeeze any excess water from the swab. Clean the face and edges of the inkjet print cartridge as shown. DO NOT wipe the nozzle plate. Hold the inkjet print cartridge up to the light to inspect for fibers on the face and edges. If fibers are still present, repeat this step.

2. Install the inkjet print cartridge in the printer and load paper in the paper tray.

3. Turn off the printer.

4. While pressing the Change Cartridge button

( ), press the Power button ( ) to activate the cleaning process. A page will then be printed. If the print quality is unsatisfactory, the inkjet print cartridge may be out of ink. In this case, use a new inkjet print cartridge.

Printing from DOS

What is a printer driver?

If you use DOS software programs (whether or not they are running within Microsoft Windows), you need a specific printer driver for each DOS program in order to print to your HP DeskJet 420 series printer.

A printer driver is software that allows you to access your printer’s features from within your software program’s print menus or selections.

Why do I need to contact the software manufacturer?

DOS software manufacturers provide and update printer drivers for their DOS software programs. In DOS, each program is developed independently under different development standards. Therefore, the software manufacturer is able to tailor the printer driver to work specifically with their software program. The software manufacturer uses HP’s printer language, called PCL, to develop printer drivers for HP DeskJet printers. Therefore, you can sometimes use a different HP DeskJet printer driver to print. However, the best driver to use is the one designed specifically for the HP DeskJet 420 series printer. Some drivers are simply renamed from previous drivers.

Why isn’t there a printer driver for my brand new printer?

The software industry is moving toward development of individual software programs under a common set of development standards. The most common standard is Microsoft Windows. HP uses this common development standard to supply a printer driver for use with all Microsoft Windows compatible software programs. This is the reason that fewer DOS printer drivers are being developed over time.

If there is not a DOS printer driver for my new printer, is there another printer driver I can use instead?

Selecting a printer driver for the HP DeskJet 420 series printer in each DOS software program that you use ensures the best support for your printer. If there is not a printer driver available within your program for the HP DeskJet 420 series printer, select one of the following drivers.

Printer Driver Level of Support

HP DeskJet 500C/540 Most black or color printing features HP DeskJet 340/320/310 Most black or color printing features HP DeskJet 400 Most black or color printing features HP DeskJet Portable Most black printing features HP DeskJet 520/510 Most black printing features HP DeskJet 560C/550C Most black printing features HP DeskJet 500/PLUS/HP DeskJet Some black printing features

How do I install DOS printer drivers?

To install the DOS drivers listed in this document, follow the instructions supplied by the software manufacturer. If you have questions or concerns about the performance of your printer when using one of these drivers, contact the software manufacturer.

Potential for Radio/Television Interference (U.S.A. only)

The HP DeskJet 420 printer generates and uses radio frequency energy and may cause interference to radio and television reception. Your printer complies with the specifications in Subpart B of Part 15 of the Federal Communications Commission rules for a Class B computing device. These specifications provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation. If the printer does cause interference to radio or television reception, which can be determined by turning the printer off and on, you can try to eliminate the interference problem by doing one or more of the following:

■ Re-orient the receiving antenna.

■ Re-orient the position of the printer with respect to the receiver.

■ Move the printer away from the receiver.

■ Plug the printer into a different outlet so that the printer and receiver are on different branch circuits.

To comply with FCC rules Part 15B Class B computing device, use only shielded interface cables.

Compliance Statement (Canada)

This Class B digital apparatus meets all requirements of the Canadian Interference-Causing Equipment Regulations.

Cet appareil numérique de la class B respecte toutes les exigences du Règlement sur le matériel brouilleur du Canada.

Power adapter statement

The power adapter cannot be repaired. If it is defective it should be discarded or returned to the supplier.

Das Netzteil (einschließlich Kabel und Adapter) können nicht repariert werden. Falls ein Teil des Netzteiles defekt ist, die ganze Einheit wegwerfen und durch eine neue Einheit ersetzen.
