9 dots on three rows. Join all the 9 dots by 4 straight lines (continuing straight lines) without going back.

Yes, you would set the guide at the distance you want the next row to appear. Set the guide to follow the previous row and then stitch with the walking foot to create the new row.

You have to go beyond the dots not just stay within them. For example start at the lft hand bottom dot and go up through the other 2 left hand dots ond keep going to towards the top of the page. Come down at an angle to the right and go through just one or two more dots not neccessarily under each other etc. The secret is (literally) THINK OUTSIDE OF THE BOX.

Ideal question for Google. You get hundreds of hits in less then a second. Take one and it saves me to type over a complete page.

Sympton: Horizontal misalignment of characters (Dots or characters move left or right from dot row to dot row or line to line)

NOTE: to check the phasing value, power down the printer, remove
the shuttle cover, and read the phase value on the aluminum
shuttle casting in a black marker. Should start with PH... You will need this number below!

IMPORTANT The printer must be printing the Phase pattern of “H’s” when the Phasing Value is changed, or the New Phasing Value will not be written into NVRAM. If the value is changed when not printing, the printer will return to its default phasing value when powered off then back on.

1. Raise the printer cover.
2. Install the ribbon.

A line on a LCD screen (like a laptop) is caused by a faulty power connection in the screen.

Usually a entire row or column will not activate causing a black line to show. When you closed your laptop, the screen is powered down. When you opened it back up, the screen would be reinitialized and it appears that you lucked out on your issue.

When a row or column fails it is usually a permament failure that can only be fixed by a monitor technician or a screen replacement.

A similar failure can happen that causes black dots to show on the screen. These are burnt out junctions where the rows and columns meet together. The dot is commonly called a pixel.

pick the lines that are most in a straight line.. click the dot in the circle and so on

This is the add toner light. Replace the tube of toner and will be well.
