Vertical dark streaks on one side of page on brand new Ricoh SG7100DN with new inks

Hi everyone,

I was looking for some advice on a printer issue i've been having with a brand new Ricoh SG7100DN and brand new set of Sawgrass inks. Its the second brand new Ricoh that has had this problem and although Sawgrass have been extremely helpful, nothing they have suggested has worked to fix the issue or even improve it slightly.

I'm getting these horrible dark streaky lines (pictured) on one side of my prints. It's in the same spot on a page every time and pretty much runs across the full vertical length of that side of the page and in that area although certain areas aren't as noticeable further up or down.

Half of the page prints perfect and the other always has those same dark streaks no matter what settings or adjustments you make. It's like the paper roller is pressing down way too hard on one side before the ink has time to dry and is causing lines which are impossible to avoid. They show up on everything i sublimate which is a nightmare. Out of desperation i'm printing my mug templates on just one side of the paper (the side without streaks) as i can't afford to stop production.


I have attached a photo of what is possibly the best example of the streaking issue as it's an extremely hard one to capture on a regular camera. I borrowed a professional SLR from a friend to take this photo and i'm so glad i did because it shows you the true scale of the problem.

I have preformed all the usual troubleshooting steps and currently:

The Nozzle check is perfect,
Print head positions are perfect on all quality settings,
The paper feed adjustment is perfect,

This is the second brand new Ricoh i have had which has this problem straight out of the box and the streaking area on this printer is in pretty much the exact same spot as it was on the previous printer. Everything is set up correctly as one half of the page prints perfect and the issue occurs on any image you print (i have chosen the orange one as it shows up the clearest). I can't see the streaking on black but i don't know if thats ebcause it's to dark to see.

Another thing to point out is that the streaking although it looks brownish is actually a darker shade of whatever colour was being printed at that moment the streaking occurred. For example, the dark streaks you can see in the image are actually a darker orange and not brown as they appear.

Has anyone come across this problem before? I'm having the worst luck with Ricoh printers. Any help would be most appreciated. Many thanks. :)

No picture....

You can't see the picture? Its in the post for me? I'll post it separately

Have you used the same paper in both printers ?. Worth trying a different image, colour etc. Presume a head check comes out clean.

Hi, thanks for the reply. I am using the same brand of paper (Trupix Classic) but a different batch to the one i used on the previous printer. Head check is perfect and this issue occurs on all images and colours except for black, from what i can see anyway. It might just be that the black is too dark to show the lines. As mentioned though, one half of the paper prints perfect. The two images above are side by side on the same page and the image on the right is fine.

Only thing I can think to try is changing paper thickness in the driver from standard to thick but clutching at straws really. Perhaps try a sheet of ordinary plain paper as well. To have this issue on two printers is quite odd which almost rules out hardware unless you have been very unlucky.

Change the driver setting to quality priority and untick the quick paper feed in paper tab.

Seen this many times I had this on a 3110 which ricoh replaced under warranty. Send it back get it replaced they have head issues on a lot of machines.

Perhaps a recent post we started (and resolved) may help:

Hi thanks for the help guys, as this is the second replacement SG7100DN that has had this issue it doesn't seem like Sawgrass are willing to replace another. Its really unfair to have spent this much money on equipment and to just be left in this predicament by the supplier (Subliblanks). Nothing i do seems to get rid of this nasty issue.

I would not have thought that Sawgrass can refuse to replace another faulty printer. £700+ is a lot of money and I would be having a chat with trading standards. Quite possible that subliblanks hands are tied as the warranty is with Sawgrass.

Yeah it's true. I mean i haven't asked out right yet. Sawgrass were kind enough to replace the first one but now they want me to send my current one to them to look at and i'm worried about doing this as the last time i sent an item off to a supplier to look at (my adkins mug press to Xpres) 'they made me fill out a form to say they were not liable for damage, so i made sure the item was so heavily padded and protected that you could drop the box holding the press on the ground and its contents would be fine...yet the press came back with a big dent on the back like someone smacked it against a table or something. These SG7100DN printers are huge fragile.

Both new SG7100DN's 100% have the exact same problem...it looks like the rollers or something are leaving marks on prints on both. I'll call Sawgrass on Monday and see if i can get another one swapped out but i have a horrible feeling that the same thing is going to happen with the next one they send, its like a manufacturing fault or something. It doesn't matter what settings you use, what paper type is selected, what paper is used, what side you print the image, what image is printed, what colour you use (harder to see on some shades but is still there), how many maintenance procedures you run it makes no difference, the lines are always there and in the same area.

Here's a picture i've just taken showing the issue across a few colours...the lines are so hard to see in photos but they run throughout the entire image in bars and seem to be spaced every few CM's or so and are the same width. I've included a close up of the bars of lines and drawn on red lines showing roughly where these bars of lines run through the pages. Has anyone purchased a new Ricoh SG7100DN in the last couple weeks/month and experience this issue? It seems to strange that i'm the only one with such a business crippling issue and have been unfortunately enough to experience it twice, both on new printers.
