We understand that the blue handle on your printer is missing. We don’t think it was misplaced by the manufacturer, as they check each printer thoroughly before sending it to customers. Now, the white peg is the support that is holding your tray. Check the solution specified below to clear this issue.
Pull the front door of the printer.
Take a look at the printer when you are opening it, the side with the peg should move around 1/4 in the upwards direction.
Since the printer is turned on when you do this, the control panel should display the message Front Door Open.
If the tray does not move up while opening, then you will be unable to change the cartridges.
Check if you have opened the door completely and the peg is removed from its place. Verify if the drawer can be pulled out smoothly.
