Locate the two headlight lens assembly retaining screws at the top of each side of the assembly.
Remove each screw with the ratchet and a suitable socket.
Place the screwdriver behind the lens assembly to assist in prying out the guide pins that secure and align the headlight assembly. Hold the lens assembly from the outside edge (marker light/directional light section) first and pry from behind with the screwdriver to unseat the guide pins. Pry from the inside end of the lens assembly to unseat the other guide pin.
Pull the lens assembly out far enough to reach behind it and disconnect the headlight bulb wire harness from the back of the bulb. Or simply remove the bulb by twisting the harness and retaining ring counterclockwise and remove it as an assembly.
Turn the marker light/directional light socket and wire counterclockwise to remove it from the headlight lens assembly.
Remove the assembly from the front of the Stratus.

Look at the top of the headlight assembly. There is a plastic panel on top of the assembly that is held in place by two plastic pins. Remove those pins by lifting the center of the pin and then pull out the pin. Remove the panel. Then you will find two small plastic levers that will lift about 1/2 inch. They do not come out but they will release two studs that secure the assembly. After the assembly is released, slide it forward to access the bulbs you need to replace. Installation is the reverse of these procedures.

Attempt to duplicate the message by turning the printer on, reloading the media, and printing several test prints.
Note the movement and position of the carriage when the error occurs.
If the carriage stops on the left-hand side (roughly 12 inches from the ink supply station), unplug the power cable from the printer, open the top cover and try to move the carriage to the right. Closely inspect the ink tubes for wear, and check for ink tube binding or catching on the tube guide (stopping/hindering carriage movement). If true, continue with the remaining steps below.
NOTE: If the steps above do not describe the issue correctly, refer to the work instruction for a typical “Switch Power Off, Check Printhead Path” message (bpp90070).
NOTE: If the printer is installed on a Multi-roll feeder accessory, some additional disassembly is required to gain access to the printer. Instructions for multi-roll disassembly are listed at the bottom of this document for reference.
Clean the rear tube guide assembly with a moistened lint free cloth to prepare the mounting of the Mylar tape. Figure 1:Cleaning the rear tube guide assembly
Remove the backing on the Mylar tape and align the line on the tape with the front edge of the rear-tube guide so that the narrower section is towards the front of the printer. Do not attach the tape yet. Figure 2:Aligning line on Mylar tape with front edge of rear-tube guide assembly
NOTE: Ensure that the Mylar film is perfectly aligned with the rear Tube Guide surface with no protrusions or unevenness.
Carefully position the Mylar tape about 1/4 of an inch from the left-end of the rear-tube guide (do not go all the way to the end as the beveled edge will cause crimping of the tape). Figure 3:Attaching the Mylar tape
Ensure tape is evenly positioned and any air bubbles are smoothed out along the tape. Figure 4:Smoothing out the air bubbles along the Mylar tape (view from rear of printer)
Carefully fold under the narrow section of the tape to the underside of the rear tube guide assembly and smooth out any air bubbles. Figure 5:Installing Mylar tape under rear-tube guide assembly (view from front of printer)
The Mylar tape should look like the image below. Figure 6:Final installation of Mylar tape (view from top of printer)
Once the Mylar tape is installed, install the new Ink Tube System (refer to pages 8-53 of the Service Manual).
Following replacement, verify printer functionality.
