PiezoFlush solution was invented by and is manufactured by InkjetMall. This is an innovative solution that can be used to clean inkjet printers, flush inks from systems, or be used to safely store inkjet printers with a solution which does not promote drying out of the inkjet heads. It has been formulated for piezo inkjet heads and includes a colorizing agent so that when printing nozzle checks, the user can "see" the nozzle check patterns print. It is sometimes usedin Piezographysystems that do not use all available ink channels.
To unclog small format printers - please see our small format maintenance video. You can also install the PiezoFlush in refillable carts for small format printers. However, our special cleaning kit for desktop printers is very effective.
To unclog large format printers as well as the R3000, this is the best practice for using PiezoFlush:
- Fill a cartridge/s completely with PiezoFlush so that the chip which reads 100% full will be in sync with the contents of the cartridge. You can choose to fill an entire set, or only fill cartridges for the clogged positions. If you elect to fill only positions for the clogged channels, the other positions will circulate ink into the waste tank.
- The Initial Ink Charge is initiated either with the Windows only software utility on the R3000 and 4900, or using the LCD control panel on other PRO printer models. At this point - the inks are emptied from the printer and fresh ink or PiezoFlush is brought to the ink channels in the print head of the positions that have either ink installed or PiezoFlush installed.
- Do not yet initiate a nozzle check test nor run the head cleaning utility.
- The printer should be powered off and allowed to rest for 48 hours so that the ingredients in PiezoFlush can promote permeation into impacted pigment. This resting period will soften them. No nozzle check should yet be attempted nor any head cleaning operations.
- After 48 hours, power on the printer and the Initial Ink Charge is initiated a second time. This is the when the most effective treatment from PiezoFlush occurs. The PiezoFlush is pulled through the ink lines, ink damper and the print head with force from suction for eight minutes. Any softened pigment is brought back into suspension and passes out the print head.
- Now initiate a nozzle check to determine if any improvement is noted.
- If improvement is noted, you can alternate between regular head cleanings and nozzle checks.
The amount of PiezoFlush required varies from model to model. The best practice is to fill the refillable cart to its full mark so that the chip (which already reads 100% full) will be in sync with the cart contents. However, you can elect to under-fill the carts as long as you ignore the Status Monitor or the reported amount of ink remaining in the cartridge - and instead visually check the cartridge to make sure it does not run empty. The following is a chart indicating the amount of ink discharged per channel as well as the minimum level required to operate the cartridge for the following printers:
|Model||Qty Fluid per INIT CHARGE||Minimum QTY level in cart|
|R3000||10ml / channel (8 channels)||6ml|
|Pro 3800 / 3880||14ml / channel (9 channels)|
|4800 / 4880||18ml / channel (8 channels)||40ml|
|4900||18ml / channel (10 channels)||30ml|
|7800/7880||28ml / channel (8 channels)||40ml|
|7900||40ml / channel (10 channels)||40ml|
|9800/9880||40ml / channel (8 channels)||40ml|
|9900||40ml / channel (10 channels)||40ml|
We recommend two Initial Ink Charge Procedures for clearing clogs, one for flushing for storage, and as many as two or three for preparing for Piezography to remove all residual color pigment stain. For example, if you wish to try and clear a clog in a 4900 you would need the following minimum amount of PiezoFlush per cartridge (30ml minimum operating amount, + two times 18ml = 66ml). However, you should allow yourself overhead for running nozzle cleans and nozzle checks, and or additional Init Charges.
