Serious Color Problem

[FTrindade]

Looks like there is a lot of people with same problem.

Mine printed like two or three nice images but then started to print like old ribbon printers, colors washed out, not contrasting, no color accuracy, nothing.

Did the reset... same.
Sheets are new Zink HP Sprocket Paper, printer is cold.

Aren't there any color profiles set to be used with this printer?
Maybe by using an appropriate color profile in photoshop we could get better results?

Please help.
Thanks
Check below:

Original:

Printed:^(photo with s7 edge)

This is inadmissible even for a proof, let alone a souvenir for people...
See those "vertical lines" ?
The color rendering is horrible...

This is a reason for me to ask for a money back.

Best compliments,

Hey @FTrindade, Thanks for reaching out!

I understand you have issues printing using your HP Sprocket.

• Use genuine HP ZINK® Sticky-Backed Photo Paper. ZINK® makes custom photo paper for a variety of printers, such as Polaroid, LG, and HP. HP recommends using HP ZINK® Sticky-Backed Photo Paper for best results. To purchase genuine HP ZINK® Sticky-Backed Photo Paper, go to the HP Sprocket homepage. You can also purchase genuine HP ZINK® Sticky-Backed Photo Paper from other retailers.

• Clean the output rollers with the blue HP ZINK® Smartsheet from the same pack of photo paper currently in the printer. Load the blue HP ZINK® Smartsheet into the input tray with the barcode facing down and the photo paper with the print side facing up, and then send a print job.

   note:

  Load photo paper with the Smartsheet to avoid an Out of Paper error message.

• Allow the printer a few minutes to cool down between print jobs.

  When the printer becomes too warm, a Cooling down... Sprocket needs to cool down before printing another job. Wait to send another photo. the message might display on the HP Sprocket app. Tap OK to clear the message.

• Store the photo paper in a cool, dry place and avoid contact with water. If water spills on a photo, wipe it away as soon as possible to prevent damaging the photo.

• Use clean, wrinkle-free photo paper. Avoid loading wrinkled or curled photo paper into the printer.

• Make sure images have a minimum resolution of 818 x 1258 pixels per inch (PPI) for optimal print quality. Screen-captured images from your mobile device might not have sufficient resolution for optimal print quality. See your mobile device manufacturer for more information.

Let me know if this helps you fix the issue.

Hello @FTrindade - 

I responded to your post in the other thread, and I'll post the same response below.  Unfortunately your sample images aren't coming across for me in the forum post.  If you wish to send those to us directly, can you hit the 'Give Feedback' button in the Sprocket app, and attach them there with an explaination of the problem?  We can work on a solution with you via e-mail.

Here is my feedback from the other thread:

We absolutely value you as an HP customer and want to make sure we understand/address your concern.

First off, can you confirm the firmware that is running on your Sprocket printer?  After powering on and pairing the printer to your phone, go to menu -> sprocket -> printers -> Firwmare Version (e.g. 1.1.0).

Secondarily, today we released an updated firmware code that does have color map improvements.  You can upgrade by following the instructions below:

• First, make sure the Sprocket is charged to at least 75% battery and powered on.
• Ensure the Sprocket is paired to your mobile device.
• On your mobile device, open the HP Sprocket app and go to menu -> sprocket -> Printers; A ‘blue’ firmware update link will be present or a pop-up message will appear if an update is available.
• After clicking the link or upgrade prompt, follow onscreen process/instructions.

With ZINK technology, prints will never have the same vibrancy or contast as what you see on your phone screen, or even what you may be accustomed to with home inkjet or lab prints.   This is the nature of trading off perfect print quality for the portability/convenience of sprocket.

Please let me know if the suggestions above address your issue.

Thanks!

fyi i just bought the hsprocket and color printed way too warm (yellow).   I tried editing picture on iphone to make it more blue but again printed way too yellow--I then updated firmware as described above and this made a significant improvement in color accuracy

I have the same problems and just bought the printer today.  I've updated the firmware and there is no. Hänge in the photo output.  Am I doing something wrong, but the photos are horrible and I. Embarrassed to give them to anyone or show them.  They're awful.

Yes they look way too yellow. I did some tests before and after firmware update and did help a bit. I now edit each pic on iPhone to set color cast to full blue before printing on sprocket. This helps a lot but like hp tech support states output will not look like what one would get from non-portable printer

[esg121]

This is my resolution. For those with iPhone perhaps open pic in photos --- open edit tab---click on third icon in bottom---press on down arrow toward right of screen on color tab to open cast slider--slide cast tab all way to make pic blue cast. Printing pic this way gives me more accurate colors. But is a pain. Perhaps hp will continue to upgrade firmware for better colors
