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...

Fingers crossed that you find a satisfactory option. What was the last PC OS that gave you full functionality? Given that the K8600 was introduced in about 2007 I am quite amazed it has worked until just recently for you. Finding ink for an old model seems pretty amazing too given new models...

The link works great now

Just as an FYI, neither of the links give public access and Google Drive wants one to Request Access. Fewer people will want to go through that process is my bet - FYI

Hi @samboy Some volunteer during the week, some volunteer during the weekend, and some volunteer all week. Clearly, it's a frustrating situation. I hope you don't take this the wrong way, yet there is a parallel between your printer taking a tumble and trying to fix it over a forum and a...

Here is a link to a prior post on the same error code: https://www.printerknowledge.com/threads/canon-pixma-pro-1-error-6010.10606/ Given it took a tumble, could be a lot of different things yet I hope list in the post helps narrow down where to look John Wheeler

Hi @raztech Printers have many reset options such as for scanning , network, etc. It would help if you provided more details of the problems you are having or trying to solve. If you are trying to do a product check, here are the steps and if should get to the point where it prints a nozzle...

Great inputs thanks. John Wheeler
