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. |

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 |

Much less hassle m Totally agree. My last freaking piece of **** printer was an Epson. The damned 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 pages, was silent as the night, and never gave me trouble. I stupidly retired it when color injets became cheaper. That was the beginning of the printer 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 cartridges jamming up or refusing to identify themselves as authentic Epson cartridges. The laser printer is the closest thing to my old Deskjet for reliablility, and it's a hell of a lot faster than any comparable injet. |

Tell me more about the re-inker. I am still using an NEC Pinwriter P5200 !! Colin 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. You can go further by adding a tiny plastic offcut to act as a miniature funnel. 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 add ready made ink or a cheap dye. Violet is cheapest but fades right away in time. Costs vary a lot per colour. 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 it. |
