What resolution for printing purge patterns?

If I’m not going to print on my R1900 for a short while, but not long enough to warrant inserting cleaning carts, I will often print the occasional calibration chart on plain paper to keep the ink flowing and cartridges agitated. I do so at 720 dpi to conserve ink. Is there any benefit in doing so at 2880 dpi? I am assuming that all nozzles are used at 720 dpi, but given problems that I have had in the past with clogs I wondered if that assumption is correct? Sorry if this is a dumb question.

(As you will see from my order history, I have just ordered and installed fresh inks and carts, and so am not having this problem at the moment. But it just occurred to me that this might have been an issue.)

Hi Brian~

Making a weekly print at 720dpi will be fine for this purpose, and I recommend agitating your carts every 1-2 weeks. Depending on how long the printer will not be used, it will be easier to simply flush the print head and turn the printer off while unused (storing the carts in sealed bags to prevent drying). You will want to weigh out the cost of getting a set of flush carts (which can be reused many times) vs. the time and costs involved in making prints, using your quality Piezography ink.

I hope this helps, all the best~ Dana :slight_smile:

Thanks. I have a set of cleaning carts, but I find it’s only worth putting them in for longer periods.

I thought that on the desktop printers, the cartridge movement back and forth when printing a nozzle check and a calibration chart was enough to keep the inks agitated, if done sufficiently regularly, unlike for the larger capacity printers. I thought I read Jon saying this somewhere. Is this not the case? If not, how do you recommend agitating desktop carts? Do you mean taking them out and shaking them gently? Won’t that trigger a head clean?
