hp officejet j4540

J4540

I love my J4540 except every (EVERY) scan has a huge line running from top to bottom down the middle.

Can I solve this?  It has become so bothersome I may need to buy a new printer / scanner / copier.

Hi @PartyMarti,

 

Thank you for showing your interest in HP Support Forums. It is a great place to find the help you need, from other users, HP experts, and other support personnel. For you to have the best experience on the HP forum, you could also visit our HP Forums Guide for the First Time Here? Learn How to Post and More.

 

I see from the post that you are having scan quality issues on your HP OfficeJet 4540 printer. Don't worry as I have a few steps to help you get through this concern,

 

To provide you with an accurate solution, I'll need a few more details:

Are you able to make a copy from the printer?

Have you tried to clean the scanner?

 

In the meantime, let's start off by performing a Hard reset on the printer and make sure that the printer is connected directly to the wall outlet and not to the surge protector.

With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.

Remove USB cable, if present.

Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.

Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord and then plug back the power cord to the printer.

Turn on the printer and wait till warm-up period finishes and the printer is idle.

 

Let’s first try and make a “photocopy” to determine whether the issue is with the printer or not. Place a document on the scanner glass and choose “Copy” option. If the printer is making a good copy, then the printer hardware is fine.

 

For more details, please follow the steps suggested in the support document for - Fixing Scan Quality Issues

 

I hope this helps. Let me know how it goes for further assistance.

 

Eagerly waiting for your response!

I hope you have a good day ahead,

And Feel free to ask your queries as this forum has some of the best people in the world available and ready to help.

Hello Jeet and thank you for reaching out.  The printer function works perfectly.  No down the middle of the reproduction.

I work from home fulltime and put  the J4540 to good use for all functions except fax.  I will look at the procedures you have for me to do but I want you to modify the instructions in light that the copy function and the print function works fine.  I would not like to go through procedures that are not required baced on this feedback.  Thank you very much!

Hi @PartyMarti,

 

Thank you for replying,

I appreciate your time and efforts,

 

As I understand both copy and print works fine only issue with the scanning function. I would like to check with you if this is happening from the flatbed or from the ADF.

I would suggest you to Clean the plastic and glass strips inside the document feeder with a soft, lint-free cloth sprayed with glass cleaner.

 

For more steps, please follow the link.

 

Alternatively, you can try to make a copy from the ADF and check if there is a line from the top to the middle. If there is a line while copying from ADF, then this is a hardware issue.

 

Please do perform the steps I had suggested as well and get back to me with the results for further assistance.

 

Regards,

Hi @PartyMarti,

 

Thanks for the update,

I would suggest let's start by cleaning the scanner glass as well as the strip on the ADF using lint-free cloth sprayed with glass cleaner.

After which I would suggest you try to scan and check if that helps.

 

Next thing, I would suggest is to perform a Hard reset on the printer, for more details, please follow the link for the rest of the steps.

 

If the issue still persists, I would suggest this could be a printer hardware. I would recommend you contact our HP phone support for available service options. If your product is out of warranty please choose paid options to get the tech support number.

Hello Jeet,  

I cleanded the ADF feeder and the clear plastic film on the cover underside because a transferof black materials had occurred.  I had to gently lift the plastic film that is tucked under the white platform to clean the area not otherwise accessable, then tuck it back in.  The scans now do not have a line and so I am back in operations.  Simple fix, just required curiosity and some encouragement.  Thank you!
