Blocked ink-jet nozzles

2 Canons, MP272 and MP495 Both unused for years, both the same total lack of yellow printing. , either m/c even swapping carts. Folded tissue dampened with cleaning fluid, pressed against the nozzle plate, suggestive of not being a lock-in "fault". 2 minutes in an ultrasonic bath ,canted over to the yellow side, in methylated spirits. Both now fine photo-grade output, with refilled carts.

Yes. Ultrasonic cleaners can be very close to magic if properly applied.

Mine gets very little use, but the top, conveniently glass for would-be viewing, is all crazed/micro-fractured? Is that common with such cleaners, partially self destructing? If I want to see whats going on, I have to find a piece of glass or perspex to cover over the dancing fluid fountains.

I should have said , with the damp tissue test, showing yellow staining on the tissue. Also locked-in , meaning makers trying to defeat cart refilling, to force purchase from them. Another tip, I don't see with ink refill kits, they always seem to say drill in . That must leave plastic swarf inside. I use a conical soldering iron tip at the breather hole , to melt in. Then when closing , a short length of spaghetti tube inserted and then hot melt glue around it and marginally into the plastic of the cart, so easily pulled away the next time.

Better laser printer refill companies often sold a soldering iron with a round tip to melt a proper hole. And included a plastic plug so you could more easily refill in the future.

Can you pour toner through a hole without mess? (Only laser printers I've ever used have been looked after for me!)

Yes, toner bottle has a screw on funnel. So the mess factor is minor if at all.

My current work printer, an HP something or other, does not have the inkjets in the cartridges. I only use black ink and so only refill the one cart. Instead of drilling a hole I add the ink through the absorbent pad on the bottom of the cart that delivers ink to the printer head. I add ink one drop at a time and it is fascinating to watch it soak in. The ink spreads across the complete pad surface almostly instantly and then soaks in almost as fast. As the cart gets fuller the ink is absorbed more slowly so it is easy to tell when the cart is almost full. Much easier than my home printer where I have to add ink through a drilled hole using a syringe. Eric

For the usual padless carts I use a length of spaghetti tube as a dipstick , when filling from syringe, rather than cc markings on the syringe.

There seems to be a hydrophobic surface to the nozzle plate of these carts, I suppose some sort of nano material coating

if you do only occasional printing and in BW only, really get yourself an inexpensive LASER printer.

Much less hassle

That is what I did. Found an all in one laser printer on sale. I just got tired of having the HP printres quit because the ink was too old. I really like the options on the Samsung I got. It will automatically print on both sides or I can reduce the print and put 2 or more pages on only one side of the paper.

inexpensive LASER printer.

Totally agree. My last freaking piece of shit printer was an Epson. The d amned thing said it was down on one color (allegedly) and not only would it refuse to print in B&W, but refused to even scan documents until I gave it it's cyan fix.

My first printer was a HP Deskjet 500 and that thing would print tons of pa ges, was silent as the night, and never gave me trouble. I stupidly retire d it when color injets became cheaper. That was the beginning of the print er wars with me as the French resistance.

I picked up a cheap HP B&W laser printer two years ago and won't ever look back. I don't need color and I don't need to worry about half full ink car tridges jamming up or refusing to identify themselves as authentic Epson ca rtridges. The laser printer is the closest thing to my old Deskjet for rel iablility, and it's a hell of a lot faster than any comparable injet.

I use the refilling syringe on the felt pad - but it has to be done slowly.

My last Epson was DM with a ribbon cartridge.

I fitted mine with a re-inker. But eventually ribbon wear causes pin jam.

Tell me more about the re-inker. I am still using an NEC Pinwriter P5200 !!

Ah, multipart forms presumably. Put a full height pad inside the cart where the ribbon would be pulled past it, either on the ribbon output or input, I forget which. Drilled a hole in the cart top for ink & countersunk it. Yo u can go further by adding a tiny plastic offcut to act as a miniature funn el. Now just put however many drops of ink in the funnel and it reinks the ribbon as you go. There is some tendency to reink a third of the length and not the rest, so little & often rather than one big glug.

ISTR a mix of printer's ink & meths being good, though you can use cheaper mixes. I'm pretty sure I used to use paraffin as the liquid base. You can a dd ready made ink or a cheap dye.

Violet is cheapest but fades right away in time. Costs vary a lot per colou r. They're the same price per gram but violet goes a lot further than black . For dark colours, mix red, green, etc then add a little black to darken i t. Here we go: blue is the cheapest permanent colour. Pence per amount of result: violet 13 blue 17 red 21 green 25 yellow 35

There is a major problem with reinking to beware of. As the ribbon wears at some point it can catch a pin occasionally. This kills print heads, don't overdo the reinking.

A b&w laser no-ink printer does seem like the best bet.
