Latex 315 grey prints more like a light purple

#1 northcoastTIM a year ago

I noticed that my greys are printing more like a light purple. All other colors seem fine. I am new to printing since January and I have been scratching my head all day. I have seen other posts for other printers and I am hoping someone will have a solution for me. I have tried as a PANTONE color and also CMYK color to see if that made a difference and it does not. Any help is appreciated.

Hi @northcoastTIM,

I recommend to do the CLC, you can find more details on the user's manual. Apart from this, you need to know that grey color is one of the most difficult to print if you are not following the proper color workflow.

#1 If everything has been printing normal until now, and your using the same ICC profile, replace the LC/LM Printhead. That is your problem. Also, check the usage of how much ink has passed through that specific printhead. If it is under 1000ml, it is covered under warranty and HP will replace the printhead.

Performing a print quality optimization should show that the printhead is losing too many nozzles. Perform that on your printer, and take a picture of the solid squares that are 100% color. The LM will most likely be distorted. This will confirm the printhead is bad. HP will request all pages and pictures to be sent before they warranty the printhead.

How old is the printer? If the problem comes back shortly after a new print head is installed, follow my solution in the following thread: https://hplatexknowledgecenter.com/forum/printers/light-magentalight-cyan-pint-heads-last-only-after-one-print-job

Howdy!

I have a HP L315 showing up tomorrow and have been getting everything set up for the necessary wiring. I am a little confused however. Does each of the 2 lines need to be on a separate 220 breaker, each on a 110 or both on a shared 220? The largest draw is only 13 amps on the curing side of the printer. My instinct is that each plug only needs a dedicated 110 with 20 amp wiring. Help would be greatly appreciated.
