Deskjet F380 is normaly printing but it will print blank

If the printer is printing blank pages, make sure you are using the correct printer driver and make sure the paper size is correctly selected in the driver. If the printer is printing black only, the Ink option in the printer driver may be set to Black instead of Color or a setting in the software may be set to print black only. Also, the print head nozzles may be clogged. From the Utility section found in the printer driver, clean the print heads by performing a head cleaning followed by printing a nozzle check pattern. A head cleaning and nozzle check must be performed as a cycle. After printing a nozzle check, examine the printed dot pattern. Each staggered horizontal and straight vertical line should be complete, with no gaps in the dot pattern. If there are gaps in the dot pattern, continue with another cycle. Performing up to 6 cleaning cycles is not uncommon if the print heads are severly clogged.
