Using the Printer Cleaning Process During the printing process, paper, toner and dust particles can accumulate inside the printer. Over time, this buildup can cause print quality problems such as toner specks or smearing. This printer has a cleaning mode that can correct and prevent these types of problems. Engine Cleaning This process uses a transparency from Tray 1 to remove dust and toner from the paper path. Use this process if toner specks or dots appear on printouts. This process will provide a blank page which should be discarded. 66 Chapter 3 Printer Tips and Maintenance ENWW Note For best results, use a transparency during this process. If a transparency is not available, use copier grade paper and not bond or rough paper. Note During the engine cleaning process, the printer pulls the transparency into the printer and then stops. This is not a jam. The transparency will be slowly stepped through the printer to complete the engine cleaning. To Start Engine Cleaning Make sure the printer is turned on and in the ready state. Load a transparency in Tray 1. Press and hold the button for 10-12 seconds. Release the button. The lights will cycle from front to back until the cleaning process has completed. Note If the button is not held long enough, the printer will print a demo page rather than perform the cleaning process. Discard the blank page produced from the engine cleaning process.

Čišćenje prolaza medija pisača Ako se na ispisanim listovima pojavljuju mrlje ili točkice, očistite prolaz medija pisača. Za taj se postupak treba koristiti prozirna folija koja će ukloniti prašinu i toner iz prolaza medija. Nemojte koristiti uvezani ili grubi papir. Napomena Najbolje ćete rezultate postići listom prozirne folije. Ako nemate folije, možete koristiti medije za kopiranje (od 70 do 900 g/m ) glatkih površina. Provjerite je pisač u stanju pripravnosti i svijetli li žaruljica pripravnosti. Stavite medij u ulaznu ladicu. HRWW Čišćenje pisača Ispišite stranicu za čišćenje na neki od sljedećih načina: Otvorite HP toolbox. Pojedinosti o tome pogledajte u dijelu Korištenje HP toolboxa Pritisnite karticu Troubleshooting (Rješavanje problema), a zatim Print Quality Tools (Alati za kvalitetu ispisa). Odaberite stranicu za čišćenje. Ili Na upravljačkoj ploči pisača držite pritisnut gumb (Kreni) dok ne zasvijetle sve tri žaruljice (oko 10 s). Kada sve tri žaruljice zasvijetle, pustite gumb (Kreni). Napomena Postupak čišćenja traje oko 2 minute. Stranica za čišćenje će tijekom postupka čišćenja povremeno zastajati. Nemojte isključivati pisač dok se postupak čišćenja ne dovrši. Možda će postupak čišćenja biti potrebno nekoliko puta ponoviti kako bi se pisač temeljito očistio. Poglavlje 5 Održavanje HRWW
