As this is just a forum its difficult to point you to a technician. i’ve checked the HP website and they don’t have a service guide for the printer your talking about they might have one on hand if you [https://support.hp.com/ie-en/contact-hp|contact them]. other than that you may be able to look online somewhere for a teardown. if you upload some images I might be able to help too !
