Printing by type and size of media (locking trays) Printing by type and size is a way to be sure that print jobs always print on the media that you want. You can configure the trays for the type, such as plain or letterhead, and size, such as letter or A4, that is loaded in them. If you configure the trays this way and then select a certain type an[...]

Feeding media from tray 1 manually The manual feed feature is another way of printing on special media from tray 1. Setting MANUAL FEED to ON either in the printer driver or at the printer control panel stops the printer after each job is sent, allowing you time to load special paper or other print media in tray 1. Press ( S ELECT button) to contin[...]

Selecting the correct fuser mode The printer automatically adjusts the fuser mode based on the media type to which the tray is set. For example, heavy paper, such as card stock, might need a higher fuser-mode setting in order to make the toner adhere better to the page, but transparencies need the LOW fuser-mode setting to avoid damage to the print[...]

Information also appears about non- HP print cartridges. ● HP print cartridges ● Non-HP print cartridges ● Print-cartridge authentication ● Print-cartridge storage ●[...]

Print-cartridge life expectancy The life of the print cartridge depends on the amount of toner that print jobs require and the length of life for the components inside the cartridge. When printing text at 5% coverage (typical for a business letter), the HP print cartridge lasts an average of 6,000 (Q6511A) or 12,000 (Q6511X) pages. At any time, you[...]

Cleaning the printer Over time, particles of toner and paper accumulate inside the printer. This can cause print- quality problems during printing. Cleaning the printer eliminates or reduces these problems. Clean the paper path and print-cartridge areas every time that you change the print cartridge or whenever print-quality problems occur. As much[...]

4. With a dry, lint-free cloth, wipe any residue from the paper path area and the print cartridge cavity. 5. Reinstall the print cartridge and close the top cover.

Engine control system The engine control system coordinates all printer functions, according to commands that the formatter sends. It drives the laser/scanner system, the image formation system, and the pickup/feed/delivery system. The engine control system contains the following components: ● Dc controller ● High-voltage PCA Figure 5-3. Engine[...]

Laser/scanner system The laser/scanner system receives video signals from the dc controller and the formatter and converts the signals into latent images on the photosensitive drum. Figure 5-5. Laser/scanner system 68 Chapter 5 Theory of operation ENWW[...]

Pickup/feed/delivery system The pickup/feed/delivery system consists of several types of feed rollers and sensors. The dc controller uses two motors and two solenoids to drive the rollers. Three media-detection sensors detect media as it passes through the printer. If media does not reach or pass each sensor within a specified time period, the dc c[...]

Image-formation system Laser printing requires the interaction of several different technologies, including electronics, optics, and electrophotographics, to provide a printed page. Figure 5-7. Print cartridge diagram Each process functions independently and must be coordinated with the other printer processes. Image formation consists of the follo[...]

Step 1: Primary charging Dc and ac biases are applied to the primary charging roller, which transfers a uniform negative potential to the photosensitive drum. Figure 5-9. Primary charging Step 2: Laser beam exposure The laser beam scans the photosensitive drum to neutralize negative charges on parts of the drum. An electrostatic latent image is for[...]

Step 3: Developing The developing cylinder comes in contact with the photosensitive drum to deposit toner onto the electrostatic latent image. NOTE The charges on the exposed area of the drum are shown as positive in Figure 5-10. Developing . The charges are actually negative, but they are more positive than the charges on the developing cylinder. [...]

Step 5: Separation The elasticity of the print media causes its separation from the photosensitive drum. A static charge eliminator aids separation by weakening any electrostatic adhesion. Figure 5-12. Separation Step 6: Fusing The dc negative bias applied to the fusing film strengthens the holding force of the toner on the print media and prevents[...]

Step 7: Drum cleaning The cleaning blade scrapes the residual toner off of the photosensitive drum and deposits it into the waste toner case. Figure 5-14. Drum cleaning ENWW Image-formation system 75[...]

Print cartridge memory system The memory tag is a nonvolatile memory built into the print cartridge. The cartridge usage condition is detected as the engine controller reads or writes the data stored on the memory tag. The engine controller renews the information in the prescribed timing and reads or writes it from or to the memory tag. The engine [...]

Print job is extremely slow. Cause Solution The job might be very complex. The maximum speed of the printer cannot be exceeded even when more memory is added. Printing speeds might be automatically reduced when printing on custom-sized media. Note: Slower speeds are expected when printing on narrow paper, when printing from tray 1, or when using th[...]

The printer prints, but the text is wrong, garbled, or incomplete. Cause Solution The printer cable is loose or defective. Disconnect the printer cable and reconnect it.
