You already mentioned eco tank type printer. Typically those are higher upfront cost and then low cost per page. What are you other must requirements for the new printer. What size paper is a must have. Do you need an all in one with scanner, copying (2 sided), fax Do you have any high volume...

I originally compiled this information for my understanding but thought it might also be helpful for other Epson P900 users. The P900 offers multiple print quality output dpi settings and other options below that were evaluated for print speed. Options included in the speed testing were: BEO –...

Thanks, @Ink stained Fingers I think others who visit this thread will appreciate the extra links. John Wheeler

Thanks for jumping in @Ink stained Fingers Good to know about some of the benefits of overcoats. Do you remember what papers you tested, and did the positive impacts extend beyond glossy papers, such as with a luster paper? It makes me wonder how much help the deepest BEO on the Epson P900...

Your welcome @beebill I am leveraging the link from a prior post by @Ink stained Fingers so he deserves the kudos for previously providing the link. John Wheeler

Hi @ruuduitdegraaf You are correct that it does not concern L values much. Yet, don't throw out the baby with the bathwater (yet). Remember that I only test L values on Ultra Premium Luster Photo Paper. The most significant impacts in secondary areas come on paper with a higher beginning...

Here is another link quoted by many in prior posts on this site. An article by Anders Torger. It s a good read as well: https://torger.se/anders/photography/argyll-print.html John Wheeler

Hi @beebill. There are a lot of experts on this site, so I am sure you will get good expert opinions. I am not one of the experts. However, I would like to put an option out you should consider if you have not already. With the cost of a photospectrometer to do paper profiling on your...

I use an Apple Silicon M1 Mac Book Pro on Sonoma 14.7 OS Photoshop 2025 and an Epson p900 printer. I have been using Macs ColorSync Utility to print some grayscale color targets, as it has a specific mode for that purpose. I hope that was the correct choice, yet if not, I will have to...

From the name, you might think it has to do with black levels - and it does - a bit. Before the details of the experiment, here are a couple of updates. 1) I changed the secondary axis from the prior post from -0.4 to 1 to -1.0 to 1.0. The graph for delta L is a little more compressed, so...

I would have gotten to that point quite a bit earlier than you. Here are my thoughts, yet topics can only be answered by you. Many projects come down to tradeoffs among scope, schedule, and resources. What is the scope that needs to be done (more than you thought and uncertain how much more)...

Hi @ruuduitdegraaf I understand the direction you are taking. The light gray ink usage drains at about twice the rate of my other P900 inks. However, a couple of things to keep in mind. I am only evaluating gray levels in one type of paper. Gloss overcoats have their place with high gloss...

I agree with @nerdful1 snd @x64 bridging the breaks with short wires would be most reliable. Using a soldering iron made for electronics is better than the household soldering gun. I don’t know what components are in the board yet some electronic components are sensitive to heat and...

If you don’t have a P700/P900 printer, you might want to skip this post. I've been testing the print output from the P900 to better understand some of its features beyond the marketing descriptions. This post is the first of several planned posts with this one focusing on the Black Enhance...

I don't have anything to add other than that I am amazed and impressed by your persistence, and I am watching as a spectator. If you pull this off and breathe life back into the printer, I think it will be something akin to this clip ;) https://tinyurl.com/3zdn8eu2 John Wheeler

That's all above my pay grade. From an engineering standpoint, I believe it is a must that the disk is secure and stable relative to the axle upon which it spins. I would also guess this mechanism has to do with the paper positioning as it is pulled through the printer, and its accuracy could...

And here is a more clear picture from another Canon similar printer:

Well, that's a big clue ;) Look for the part holding the disk on it might not be the same as the one on the left, yet I bet it was some metal part that hold it in (snap ring at least). Here is an image from the disassemble post elsewhere on this forum showing what should be there. Such a...

If you need inputs from the members on the forum, if you list all yor requirements I bet you will get inputs e.g. copying, scanning, fax? double sided printing, size job capacity (how much paper it holds) and the importance for good photo quality, etc I would also make sure you check into the...

Did you save your backups when you were on Windows 10? You would still have the drivers on the backups. You can go back to Windows 10 and run it from there. If you need Windows 11, you could use an inexpensive computer running Windows 10 in isolation to run your printer. Just trying to be...
