Printhead for HP OfficeJet 3610 and 3620

The Graviton CZ291-80004 is a replacement printhead designed for HP OfficeJet 3610 and 3620 printers using the HP960 model. It suits offices or home users who need to restore print quality on these specific inkjet machines. The unit operates on 110 V power and combines plastic and metal construction.

Behaviour during extended print runs

The printhead maintains consistent output across long documents without the streaking or colour shift that signals a worn nozzle plate. Heat buildup stays within normal limits for the HP960 platform, so the part does not trigger thermal shutdowns during batch printing. Ink flow remains steady because the internal channels match the original fluid dynamics.

Installation notes and common issues

The printhead drops into the carriage after lifting the access latch; no tools are required beyond opening the printer cover. Alignment runs automatically once the new head is recognised. The most frequent problem is the printer failing to detect the replacement, which is usually fixed by reseating the head and cleaning the electrical contacts on the carriage.
