= Inkjet Printer Tips - Part II =
If you are fortunate enough to have a spare set of cartridges for an old printer, if the backup set has already been opened and used it will typically dry up and become garbage in short order. Some people use a combination of plastic and tape to keep the cartridge's printhead sealed. For me this hasn't worked well, probably best for short term storage, not long term. Depending on the cartridge structure, if it's a sponge filled inkjet cartridge, the 'lid' of the cartridge can often be removed with a hobby knife. Physically remove the sponges, rinse out and save the ink in your refill jar. Thoroughly wash out the sponges, ink collection well and printhead of the cartridge with warm water and allow them to fully dry. Now they are like new, never filled, and available indefinitely as a backup. To prepare for use just re-insert the sponge, tape or hot glue the removed 'lid', inject ink and prime the cartridge.
Although likely hard to reach, periodically clean the printer's printhead parking position rubber cap with a moist cotton rag. The rubber cap needs to be in reasonably clean condition so the printhead seals effectively when parked, otherwise the nozzles may dry out. The printer's ink discard tray and any soaker pads should also be quick cleaned periodically with a scraper or rags. If it's an old or high use printer, excess discard ink may overflow and mess up the printer or desk or prevent the printer from properly swiping clean the printhead. It's disgusting how much ink is wasted during the printer priming process. Excess salvaged ink is saved in a recycled glass pickle jar, diluted with water slightly and used for caligraphy and quill writing projects.
For years i've also been keeping all opened ink pens, felt pens, highlighters, markers and small glue bottles in recycled glass pickle jars. A small, damp scrap of cotton cloth is placed in the jar and the humidity level is monitored every couple weeks. Re-moisten the cotton cloth if it's dry. If there is visible moisture on the sides of the jar then it's too wet, let it dry somewhat to prevent mold and mildew. Pens can be stored in this environment seemingly forever without degradation of performance.
