N&J Inkjet Trouble Shooting Guide

This section provides Troubleshooting Advice will resolve the common issues that occur .


We would also like to answer a question many customer ask about using compatible or re manufactured Inkjet cartridges in their printer's.

Will using an aftermarket Cartridge's invalidate my printers warranty? The answer is no, your printer manufacturer will try to claim they can, however they are not allowed to do so unless they can prove that using a compatible has caused the damage.
Compatibles have proven to be extremely reliable and certainly will not harm your printer in any way.

We suggest you keep your originals and keep them to one side and in the event that your printer goes faulty under warranty period simply re install them, that way they will have no reason to invalidate your warranty!

Compatible Cartridges not recognised:
If you have an Epson printer, then first of all ensure that the small plastic wedge has been removed from the clip on the side of the cartridge. If this hasn't been removed then the cartridge will not fit into the printer correctly and therefore it causes a recognition problem.

If you have a non-Epson printer, or have already removed the wedge then can you please try the two following solutions to reset the printer and in most cases it will resolve the issue:

1: Take all of the cartridges out your printer, once all of the cartridges have been removed then make sure any lids are closed so you don't cause any damage to any moving part's that could be broken.

Power it down by only by the power from the mains, do not turn the power button off on your actual printer! you either unplug it from the mains socket or simply turn the switch off next to the socket in the wall. (This is called a hard reset)
While the cartridges are out of the printer give all the chips on the cartridges a good wipe with a tissue or cloth. Now wait for at least 30 minutes and then turn the printer back on and insert the full set of compatible cartridges, making sure that the cartridges are clicked firmly into place in the correct slots within the printer.

2: If you leave the printer turned on, with the cartridges installed still and then simply turn off the power at the wall, leave it for 30 seconds and then turn it back on and see if the cartridges are now then recognised okay.

Compatible Cartridges not printing correctly:
First of all make sure that the yellow or orange pull tab on the top of the cartridge has been removed.

If the tab has been removed can you please take the following steps to try and resolve the issue:

1) Carefully take the affected cartridges out of the printer.
2) Wrap some tissue around the nozzle at the bottom of the cartridge.
3) Hold the cartridge tight and give it a good shake until you see ink on the tissue and repeat for all of the affected cartridges.
4) Put the cartridges back into the printer and perform a head clean and a nozzle test print. You need to check the test print against what you see on the screen and it must all be there.
You may need to run several head cleans if the issue is persistent.
In the case of the nozzle test print being poor then simply run another head clean followed by test print, this is important procedure and you simply follow this rule until you get all the nozzle test print pattern perfect
You must not keep taking out the cartridges If your results are poor you will simply make it worse, only change them if the status monitor is getting low, doing around 6-10 head cleans in a row will more or less use a full cartridge as cleaning simply pulls ink from the cartridge into the waste sponges.

Our rules of thumb are if you put in 2 set's of cartridges and you don't get an improvement then you either have a partial blockage which may need to be treated with a special cleaner or it will simply be too hard and blocked to budge, in that case then your fighting a losing battle to cure it.

2 more simple pieces of advice to save you money!
Always leave your printer on, turning it off then back on initiates a head clean wasting ink, printers cost virtually nothing to run in standby mode.

Always change compatible inkjet cartridges before the status monitor tells you to, that is because unlike originals that have a clever venting system incorporated into the cartridge to expel air traps, compatible's do not have that so air traps can only be got rid of via head cleans, our point here is, if you use all your ink up before you change the cartridge, then you are very likely to pull air into the printers system, when you do change the cartridges then you are very likely to suffer from air traps, where as if you change the cartridges when they still contain a little ink and therefore there is very little chances of air being sucked in, then it actually works out better because your not going to need to do many if any head cleans to purge the printers system with fresh ink.

Take the following steps to clean the circuit board on the cartridges:

1) Take the cartridges out of the printer.
2) Take a piece of tissue, and if you have any, apply a small amount of nail polish remover, methylated spirits or something similar to the tissue, if not then it is fine to use water.
3) Clean the gold circuit board on the side of the both cartridges by gently rubbing with the tissue and be careful not touch the chip with your fingers.
4) Re-insert both of the cartridges and try to print a document.

Hopefully the cartridges should now be recognised by your printer, although you will find that your computer and printer may report that it is low or empty, but this is normal and you can simply ignore this and print as usual.

Canon Remanufactured Cartridges not recognised:
This range of printers sometimes does not recognise previously used cartridges until a manual over-ride is applied as follows:

1) Hold the reset button down for 10 seconds or so (the reset button is a circle with the triangle inside)
2) The carriage should begin to move and if you have an LED screen then it should now change from displaying

If this does not over-ride your printer then please take the following steps to clean the circuit board on the cartridges:

1) Take the cartridges out of the printer.
2) Take a piece of tissue, and if you have any, apply a small amount of nail polish remover, methylated spirits or something similar to the tissue, if not then it is fine to use water.
3) Clean the gold circuit board on the side of the both cartridges by gently rubbing with the tissue and be careful not touch the chip with your fingers.
