Canon printer ink absorber full


Hello, The absorber is triggered by printer count, not a moisture meter, so chances are that it is not really full. I have never cleaned or replaced my mp470 pad and have not had a problem. To by-pass the message try thie following. It works fine on my mp470 and may work on your mp280.
Waste ink full reset

These are the instructions which worked for me on my Canon pixma mp470:

1) Close the print head cover, and turn off the printer. While pressing the Resume/Cancel button, press the Power button. (Do not release the buttons. The LED lights in green to indicate that a function is selectable.)

2) While holding the Power button, release the Resume/Cancel button. (Do not release the Power button.)

3) While holding the Power button, press the Resume/Cancel button three times, and then release the Power and Resume/Cancel buttons. (Each time the Resume/Cancel button is pressed, the LED lights alternately in either orange or green, starting with orange.) During initialization, the LED blinks in green.

4) When the LED stops blinking and lights in green, press the Resume/Cancel button the 4 times. (Each time the Resume/Cancel button is pressed, the LED lights alternately in either orange or green, starting with orange.)

5) Press the Power button. The LED lights in green, and the
selected function is performed. (When the operation completes, the printer returns to the menu selection mode automatically.)

6) Power off then back on and test.

Xtreme pressure washer keeps cutting out.


If it is a gas powered machine and it cuts out when you release the spray gun trigger, it means that your unloader valve is stuck closed.
It would help to have more information about your machine and your problem. Gas or electric? Does it start up and run fine or cut out a few seconds after starting? Does it cut out when you release the trigger?
Does it cut out while spraying?

Kew Alto Force X-TRA cold water supply pressure sensor problem


Have the same p-washer (5-6 years old) and the same problem. Opened it and the pressure switch is the crook. A plastic pin has an inner and an outer spring on it (two consentric springs). The smaller inner spring is completely rusted away so the switch no longer operates correctly. Obviously the spring was of a too low quality. The service office say a new switch cost around 400NOK (50 euros) - so the washer is too expensive to mend. But I will try to get it working without the inner spring. Doubt if I succed. So will have to dump the washer.

Low pressure


if this keeps happening repeatedly it sounds like you need a new seal kit put in it can be done easily enough by you or you can get a shop to do it , if you live in a cold winter climate be sure to winterize the washer every year or keep it somewhere where it wont freeze

Pressure washer lacks pressure initially?


Dear allbusiness9,
This problem is most probably due to a faulty Spill Valve( also called Control Valve). When the gun is released the spill valve is compressed and it either closes a micro switch or just opens from the bottom and keeps the water circulating. All spill valves keep the water circulating from the bottom part. Now when the gun is pulled (opened)...the spill valve extends and closes the bottom part, and thus water goes out of the nozzel. When you work with no nozzel, there is enough water flow to close the bottom part of the spill valve. So when the nozzel is placed back there is no chance that the bottom part leaks water. When the gun is started with the nozzel....the bottom part of a FAULTY spill valve,..will colapse and pressure drops. So to fix the fault you must change the Spill Valve. In some occasions, I also found that suction valves give this problem. A faulty sucktion valve will colapse under high pressure, and lets water pass the other way round.
But in my opinion and experience, your problem is in the Spill Valve.
Regards,
Fulltech.

Pressure is fine when first started ,if trigger released no Psi


Your uplift injector valve in the water pump is sticking. You need to remove this part. Lube the top o-ring only with a water proof grease. Reinstall this part. You will be up and running again.

You need to use needle nose vise grip tool to easily remove the valve. You need to grind down the vise grip tool to fit the opening where the valve is installed.

To prevent this problem from reoccuring use a pump guard additive.
