Half of the page is black. This happens during

If it is along the edge of the print, it may be the edge of the book page you are seeing. if it is going through the text of the page, your scan carriage is likely skipping. If you don't see this on copies of single sheets of paper laid on the glass, then the weight of the book may be deforming the glass enough to catch the scan carriage as it passes. If you see it on single copied sheets, there is probably something on one of the scan rails under the glass that the carriage is "hopping" over as it passes. You could try watching the scan carriage move while holding the lid open to see if the carriage "hops" once during a scan.

it may be due to either malfunctioning of the scanner tube within the printer itself or whenever you copy a certain page the lid is not properly pace resulting to excess light on that side giving you black line when the copying is in process

A user default
1.The printer is possibly not designed to perform in color copying through the machine feeder area, only on the photograhic image scan area. Discontinue scanning the image in feed area.

A Technical default
1. The device is nearly out of ink
2. The device printing bands are clogged requires cleaning

A printing material defect
1. The positioning of the medium to be photocopied only achieves success when layed flat on the screen. Possible images are likely when lightening does not escpe in the process.

Consider, using an alternative copy machine that would achieve success.

If the color cartridge doesn't print the color bars on the alignment page (either, redish pink, yellow or blue) then the alignment process will not finish. Same for the black. If the black cartridge is printing ok, then replace the color cartridge and try this again...

SOLUTION: Start the cartridge alignment by performing a series of button presses from the front panel of the product.

• HP PSC 1200 and 1300 series:
  1. Turn on the HP PSC 1200 or 1300 series product.
  2. Disconnect the USB cable from the all-in-one.
  3. Press the sequence of front panel buttons below to start the print cartridge alignment process. The button-press sequence must be completed within ten seconds. It might take several tries to complete the sequence within ten seconds.
     1. Press and hold Cancel .
     2. While holding Cancel , press On .
     3. When the Check Paper and Check Print Cartridge lights begin to blink simultaneously, release both buttons.
     4. Press Cancel again.
     5. Press Copies .
     6. Press Paper Type .
     7. Press Color Start Copy . The alignment page will begin printing. If the alignment page does not print, repeat the button-press sequence in this step.
  4. When the alignment page has printed, place the page face down on the scanner glass and press Scan . The alignment is complete when the On light stops blinking.
  5. Reconnect the USB cable.

CAUSE: This can occur if the cartridge alignment is canceled or times out without a valid print cartridge alignment stored in memory.
