This article explains how to use the Printhead Hospital cleaning kit but we encourage you to use the printer's own cleaning routine before resorting to manual cleaning.
A nozzle check pattern will indicate which colours are blocked and offer the option of cleaning the printhead. This fires all the printheads continously to clear any air bubbles and dried ink deposits. It is reasonably effective but should not be repeated unless the nozzle check pattern improves: it uses about 10% of each cartridge and can make the blockage worse in some cases.
An alternative (and more effective in our experience) method of cleaning is to force the printer to reprime the cartridges by following these steps:
The videos show the procedure for each type of printer: the procedure is briefly as follows:
No disassembly or technical ability is required. Detailed instructions and a troubleshooting guide are included
Some printers have non-return valves or diverters (e.g. wide-format printers), so manual cleaning isn't possible. In this case we recommend using a refillable cartridge filled with cleaning solution as follows:
The following steps improve the effectiveness of cleaning but pose a greater risk of damaging the printhead.
Heating the solution to near-boiling point
Pushing 4ml solution through the head at high pressure. It may help to cut the tubing shorter so the syringe can be pushed onto the printhead more firmly.
Sucking the syringe back and forth during the first stage of cleaning (this frees up debris caught in the printhead prefilter)
The ink delivery system of wide-format printers prevents injection of fluid into the head, so cannot be cleaned with the kit
This is a common problem with Canon printers and is caused by blockage of the pressure equalising vent in the front compartment of the cartridge. Take a hot needle and pierce the top surface of the cartridge, directly above the ink outlet.
