MFC-490CW Won't print black


We are going to attempt to do a "power purge" to get rid of any clogged ink nozzles. Note, this will probably eat up about half of your ink, but that is the price you must pay in order to attempt to fix this bad boy.

1) Get into maintenance mode. Press these keys: Menu -> Black Start -> Scan x4 (hit it four times). A number pad should come up. If not, do it again.

2) Hit key 7, then key 6.

3) Press the right key until you get to "CLEANING BLACK."

4) Press 3.

5) Press Black Start.

After it purges and gets back to the main maintenance screen, press keys 9 and 9.

Let your printer start back up. If this does not work, try the above steps up to three times. If it does not work then, you need a new print head, which is not a user-replaceable part on this model.

Good luck.

Pages comes out with large black line running down page. I've tried cleaning it helps a little but I still have a black line.


If the large black line is on the back of the page, it is because too much ink is built up under the transport and transferring to the exit rollers. There is a mylar shield needed under the transport after cleaning the rollers to keep the ink from coming up again. Usually a shop repair, around $89.00

HP Laserjet 1300 yellow light STILL flashing


Re-installing the print driver will not solve a flashing light. If the printer is functionally ok, it will come to ready simply by plugging into the wall. It sounds to me like a fatal error at this point.....could be a long list of things, but I would lean towards a formatter board. bottom line with this printer at this point in it's life is, if it doesn't work, it's not worth fixing. Replaceable for about $100.

Hi please try these steps:::

Right-click the printer icon, and then select 'Properties'.
2. Click the 'Maintenance' tab, and then click 'Deep Cleaning'.

3. Select 'All Colors', 'Black' or 'Color' for the print head to be cleaned.

4. Read the message displayed, and then click 'OK'. The power lamp blinks and print head deep cleaning starts. (Do not perform any other operations until print head deep cleaning is complete. Print head deep cleaning takes about 1 minute.)

IF ABOVE STEPS DOESN'T WORK TRY THESE STEPS BELOW

Check ink tank vent hole The ink tank requires air to flow through it so ink can move from the reservoir to the print heads.

  1. Confirm there is no orange tape across the top of the ink tank

  2. If the orange tape is as shown in Figure (1), it is properly removed.

    ink_tank_tape.jpg

    *BCI-3's shown in this example.

  3. If the orange tape is as shown in Figure (2), remove the remaining tape to the level shown in Figure (1).

  4. Make sure each ink tank is snapped into the printer.

    IF THESE STEPS DIDNOT WORK THEN YOUR PRINTER NEEDS REPAIR(You might need to change the printer head.)

Scanner & black pages


The black printing usualy occurs when there is a faillure in the light, since your light is working fine, there may be a problem in the imaging device inside(camera) or the reflector. There is nothing wrong with the cartridge.
