Wierd behaviour SureColor P400

I cropped one image out of your sheet above, and will try to print it with a P400, just on normal paper which should be o.k. What program are you using to print these sheets ? I'm using Qimage and will create a layout 2x2 on a A4 sheet an print one at at time, then moving it to the next location.
Which format/paper settings are you using in the driver , and the print software ? it could be in a case of mismatch that the software prints leftover parts/edges on a next page , but this data may be blank, your printer just prints white in that case.

It only happens with back loading; the expensive paper! I hope that was clear.
I use Photoshop C2 (which is just hanging on!) but I am used to it. I don't use any of the printers own very fine tuning, just Standard 1.8 or 2.2 and Adobe rgb similarly...mostly Standard seems to come nearest to my original colours ...plus quite a lot of subtle negotiation in Photoshop! I didn't want to have to mess about with printer fine tuning every time I printed a design so it is more convenient to make all the adjustments in Photoshop and simply keep a note of which of the printers settings I used (eg Standard 1.8).
Hope that is the answer to your query. Not sure what you mean about 2x2...all my prints are different sizes/proportions. (I dislike the fact that technology seems to offer you only square formats for sending photos etc...I know it comes up in full eventually but it is still annoying).
Don't know anything about Qimage...will have a look later.

It took me a while to find the box of my P400 printer, and the rear paper feed tray, I never used that before. It just feeds single sheets, and I had to relocate the printer to get better access to the rear feeder.
I did this, I made a layout of 2 rows x 2 columns on a A4 sheet of paper and printed your image onto the top left location via the rear tray. That works fine, if I now take this sheet and re-insert it again to print onto the top right location it either won't feed or feeds and then comes back with a paper jam error via the status monitor. The error can only be cleared by cancelling the print job in the spooler window, the button at the lamp does not do much. The printer recognizes that the sheet, or part of it is preprinted and won't accept it again for another print cycle.
If I first print the image onto the top right location and then try to print in the top left location in a 2nd pass it does it on some instances but not always and comes with a paper jam message as well. Printing multiple times onto a sheet fed via the rear slot does not work just like that, you would need to find the printable areas which are not detected during the 2nd pass, e.g. starting at the bottom part of your sheet.
I tried the same via the regular paper bin, none of these problems/restrictions show up in this case. You may test this with your paper whether you can feed it multiple times via the regular paper bin instead.

I know it doesn't happen with the ordinary paper slot and Epson matt paper. I should have made it clearer about back loading.

Yes you have described perfectly what I told you has been happening. And yet I have just printed a whole page of 2 across 4 down (meaning 8 items) in back-loading. I thought I might try a different order of positioning so the first image was printed on the top left side...the second I tried to print underneath that. It wouldn't, twice. So I printed what I would normally do and printed top right. Fine!
And subsequently from left to right all the way down...no problems. (and none where it had refused first time). Wierd!
I think it also depends a bit on the dimensions of the image. Obviously if one knew what the sensors were looking for one could avoid situating stuff in the wrong place.

What is the spooler window?
Just out of curiosity what do you use the printer for, and which paper do you use?
You don't have to answer!

Anyway for most people this wouldn't occur because they wouldn't be proofing in the way I do.
And I can put up with it now I know it isn't actually a fault in the machine. The most irritating thing is the absence of a second blue which means almost any blue is printed with a heavy cyan bias and it takes ages to push it back towards more cobalt or ultramarine. Just expensive proofing. Also of course the colour on matt-heavyweight paper is duller than that on Fine-art, even quite a lot different with some colours (particularly cyan!)

Thanks for listening. Julia

Did you try to feed your special paper via the normal paper bin ? Or do you get any damage to the surface that way ?
I don't see any way to overcome this particular printer/firmware function checking the paper this way when feeding from the rear tray.

If you run Windows on your computer you easily can access the spooler window via the status monitor, there is a button at the bottom left to get to the window of the active and pending print jobs.Or via the little printer symbol in the bottom right of the Windows desktop. You can right-click onto a print job and change the status, reprinting, suspending, cancelling or printing.

I'm mainly running glossy and silk/satin/semiglossy type papers - via the normal paper bin.

I'm not clear about your problems with blue/cyan, colors look different on the monitor vs. the printout, if you activate the use of a color profile in the driver you should have a proofing option in Photoshop simulating print output on the monitor within PS. this may help you to get faster to the color you want to have printing on paper.

Thanks.
No, I haven't used the plain paper slot for my Somerset enhanced paper. The printer software makes it clear which slot you use for fine-art papers and no doubt sets the paper profile appropriately. It is coated paper and I imagine that the way the ink is distributed (for want of a better word) would be slightly different. Certainly if I accidentally use the glossy setting the result is clearly different. After all that is what the back loading is for.
I did once absent-mindedly use a sheet of matt heavyweight in the back and it made a hell of a fuss getting it out!
OK, I get the bit about the printer symbol for status check, I used to do that via going to the printer (link on my desktop)...now it is easier. The only thing is no button to 'expel' paper which doesn't want to respond to the button on the machine. I have a couple of times after cancelling been forced to go to PRINT at which point it did...in the wrong place!
Most of the time it is OK though and I wouldn't like that anyone thinking of buying this printer should be put off. They are so complicated that someone using the machine eccentrically is bound to find something the manufacturers didn't think of. So far I think it is pretty good...but don't want to tempt providence by saying more than that!
I do eventually get what I want with the blues but it is a bit of a pain ...using various Photoshop facilities ...colour balance, saturation etc. But one can't really see what is happening without printing...that is why I do so many tiny prints that all superficially look the same. Currently trying to match about 30 prints from the past so that they print as I want them to on the new printer. I am aware that had I been properly educated about paper profiles etc I would have not have this problem. But too late now! The Standard settings are pretty near...apart from the blues and a bit of plus or minus brightness etc.
Cheers, Julia. Will soldier on!

The P400 driver is recommending you to use the rear paper bin for fine art papers but you could override that selection and use the standard bin instead. You may give it a try and check wether you can see any traces of the pickup roller on the paper surface - e.g. slight abrasion. The pickup roller is about 1 1/2 inches away from the right edge and touches the paper very much at the top. The paper selection defines particular driver settings - e.g. ink saturation but the choice of the paper bin does not.

you mention that you struggle to adjust some blueish type colors such that they match your expectations on the print. You are using an older version of Photoshop, there is a pretty old plug- in available - Color Mechanic - which lets you change easily colors you select, and other colors are not affected. You can adjust the color, the lightness and intensity of the change

The software is not supported anymore as much as your Photoshop version, you may give it a try, the use is pretty intuitive, you pick a color and shift it as you want to have it. You save the image, but not any settings, you cannot do multiple images at the same time. I use once in a while -e.g. changing skin tones of people with a sun burn/tan to make them look healthier. This plug-in does not do global changes like changing the color temperature/white balance of an image. Once you know where your blue color is located on the color cube you can pull any color there.

I missed your reply...sorry. I will have a look at Color Mechanic ...always interested but Photoshop, even the old one has several ways of adjusting colour. And if I want to be selective without affecting the rest of the print, I just highlight the appropriate area area and copy it onto a separate layer, and play with that.
CS2 has been playing up for some time, no longer 'supported' by PS... but I can't afford what they would like you to do and I paid a lot for CS (£500 in approx 2004) originally (no pirating) and I am not in a hurry to pay more! Or to have to learn new tricks!
To be honest I have no idea what would happen if I had to give up Photoshop. All my prints are saved in PS. Would I even be able to open them? Ought I to be doing something about that?
As for 'white balance' and 'colour temperature', I need lessons!
Technology changes so often it is difficult to keep up with it. Everything I saved on discs is kind of out of date now because of the new settings on SC P400...so everything I do depends on what prints it. Shifting ground.
Anything you have to say will be much appreciated.
Thanks, Julia
By the way, earlier, I read you I think, saying the 60 hour limit was a myth. Because I use my printer almost every day at the moment, I do notice that it doesn't seem to spend hours licking its whiskers like the old one used to. I do wonder if there is some mechanism that 'knows' when you haven't used it enough and it needs cleaning? But you think not?

....'Color Mechanic' ...am I right in understanding that it is, or was, made for Photoshop...by Photoshop (or Adobe)? I am a bit nervous about using something unsupported as if anything goes wrong I am not clever enough to get out of trouble! I can see you can still download stuff but...mmmm.
