[SusanCrochunis]

HP Color Laser MFP 178nw, said was having a paper jam.  But when looking in HP Smart, it says I need an "imaging unit" but that I cannot fix it myself.  What do I do and how much will it cost

Hello @SusanCrochunis ,
Welcome to the HP Support Community!

1. print the supplies info report
   The imaging drum installed in this product is covered by the product warranty.
   Replacement imaging drums have a one-year limited warranty from the date of
   installation. The imaging drum installation date displays on the supplies info report.
   HP's Premium Protection Warranty applies only to the print cartridges for the product.
2. When the imaging unit has reached its end of life, the machine will stop printing. In this
   case, you can choose to stop or continue printing from the HP Embedded Web Server
   (Settings > Machine Settings > System > Setup > Supplies Management > Imaging Unit
   Stop). Turning off this option and continuing to print may damage the device’s system.
3. how to: Replace an imaging drum 
4. you need HP 120A Original Laser Imaging Drum, PN = W1120A
5. HP Store: HP 120A Original Laser Imaging Drum, W1120A 

I hope this helps. Please give me some feedback.

Kind Regards
Andr-1611
