    THanks but whether on standy or powered off it goes through a cleaning routine everytime it comes back on and so is drinking ink!

  • scandamail Jan 11, 2009

    My printer goes through the routine that you state but shows no error, however it does this every time it hibernates!

    I am away on business and will not be looking at my e-mails until Friday, in the meantime thank you for your help.

    I have the same problem, it started with a loose power cable. It got better after I removed and reinserted it, but still goes through a warmup and purge cycle at least 2x each day. The office has the ink locked up now and I cannot print until the office manager arrives and issues another single block of ink.

    I use Xerox ink and I leave it on standby never plug out, but it goes through its cleaning cycle every time it warms up. Maybe this is a Xerox way to have you buy more ink.

    Hi scandamail: Let me know if you printer does this and any messages that you get with errors.

    If printhead, ink reservoirs, or jetstack temperature are below purge

    threshold, the printer performs a head clean cycle.

    1. The printer waits for the printhead to reach its purge temperature.

    2. The printer moves the wiper to the bottom of its travel and tilts the printhead

    forward to its print position to check the ink levels. If the ink level is low, ink is

    melted into the appropriated reservoirs.

    3. The printhead tilts to the standby position and moves the wiper assembly to the

    purge position in front of the printhead faceplate.

    4. The purge pump begins the pressure purge after about 2 seconds the purge pump

    solenoid opens.

    5. The printhead tilts forward against the wiper assembly (wipe position) and the

    purge and wipe cycle begins.

    6. The Control Panel indicates the printer is performing the cleaning process.

    7. The printhead is moved left to the tilt zone, where the printhead can tilt back

    without interference, and the media path motor moves the wiper to the bottom of

    its travel to engage the printhead tilt cam. The process motor rotates the printhead

    tilt gears, which tilt in order to move the printhead to the forward print position.

    8. After the print engine is in a known, valid state the Control Panel display shows

    the warm-up progress (the Ready LED flashes). When warm-up completes, the

    Ready LED displays solid.

    9. The temperature of the printhead, drum and paper preheater are allowed to

    stabilize at their operating temperatures and ink is melted if needed.

    10. The printhead is homed to the print position for printing.

    11. A cleaning page is printed at this time, if a purge was performed.

    12. A start page is printed (if enabled).

    13. The Control Panel displays a message that the printer is initializing and then


    14. The print engine is initialized and is ready to print.

    Hi scandamail:

    Do you power off the printer every day?

    if so what happens is that everytime you power the printer on it goes through a purging routine. That means that the dry ink is cleaned from the print head. Keep your printer powered on and you should notice a difference.

Hello Phaser 8500 owners,

I found a way to restrict the wasting ink problem of excessive cleaning cycles:

Just unplug the connector of the ink pump. One can find this pump behind the left plastic cover. Unplug the connector of the pump during the excessive cycles and put it back on again after.

To my experience the cleaning cycles come too soon or too often.

Good luck,

One of the reasons this could be happening is because you are using non-xerox ink so your print head needs to clean it out much more often. Be careful using other ink as this can destroy the machines printhead which is more expensive then the machine itself to replace. What you could try is installing the new printhead firmware, it might help! Follow the link below and good luck!

    My solution is a last resort, you should never plug out a solid ink machine, it should be plugged in at all times. Otherwise it will use up loads of Ink.

Why does canon MP258 printer with scanner can't scan japanese yen paper bill amount 10,000. I tried it over 10 times but it stops,. And when i tried US paper bill, it works well. I need some explanation...

When you scan with any scanner it utilised the software with "Optical Character Recognition functions, usually abbreviated to OCR -> OCR is a field of research in pattern recognition, artificial intelligence and computer vision." to scan and record the scanned object, sometimes it does not or cannot recognise certain symbols or characters because of man made software & hardware have its limitations too.

Hope it helps.

Chances are that you didn't lock down the scanner when you moved the unit. You can attempt to open the unit and move the scanner bar manually to reset it. HPs are very difficult beasts when it comes to their power up check out. It must be fully functional...including all work in most cases. Good luck.
