A CPU is configured to control the display device to display a predetermined screen and the LED is configured to provide the predetermined notification based on a case where a predetermined condition for changing a screen displayed by the display unit is satisfied, and the CPU is configured to control the display unit to display the predetermined code in a case where the operation is received by the two-dimensional code key from the user while the predetermined screen is being displayed by the display device and the predetermined notification is being provided by the LED. ## Claims ### Claim 1 A printing apparatus comprising: a display unit; a light emitting unit; a printing unit configured to print an image on a sheet; and at least one processor operating to: in a case where a consumable of the printing apparatus is in an error state, cause the display unit to display a first screen to specify the consumable being in the error state and cause the light emitting unit to be in a first state corresponding to the error state, in a case where the consumable is in a normal state, cause the light emitting unit to be in a second state different from the first state, and cause the display unit to display a second screen different from the first screen and including a predetermined code responsive to reception of an instruction to display the predetermined code from a user, wherein the predetermined code is a code to cause an external terminal to display information of a manual of the printing apparatus by the predetermined code being captured by a camera of the external terminal. ### Claim 2 (depends on 1) The printing apparatus according to claim 1, wherein the light emitting unit is in the first state and the display unit displays the second screen. ### Claim 3 (depends on 1) The printing apparatus according to claim 1, wherein the instruction from the user is provided through a reception unit integrally provided with the light emitting unit. ### Claim 4 (depends on 1) The printing apparatus according to claim 1, wherein the display unit displays a third screen different from the first screen and the second screen in a case where the consumable is in the normal state. ### Claim 5 (depends on 4) The printing apparatus according to claim 4, in a case where the light emitting unit is in the second state, the least one processor operates to cause the display unit to display a fourth screen different from the first screen, the second screen, and the third screen based on reception of the instruction from the user. ### Claim 6 (depends on 5) The printing apparatus according to claim 5, wherein the fourth screen is a screen to notify the user to provide the instruction in a case where the light emitting unit is in the first state. ### Claim 7 (depends on 1) The printing apparatus according to claim 1, wherein the error state is caused because the consumable has run out. ### Claim 8 (depends on 1) The printing apparatus according to claim 1, wherein the consumable is a sheet. ### Claim 9 (depends on 1) The printing apparatus according to claim 1, wherein the first state is a blinking state. ### Claim 10 (depends on 1) The printing apparatus according to claim 1, wherein the second state is a turned-on state or a turned-off state. ### Claim 11 (depends on 1) The printing apparatus according to claim 1, wherein the light emitting unit is an LED. ### Claim 12 (depends on 1) The printing apparatus according to claim 1, wherein a distance between a left end and a right end of the light emitting unit is longer than a distance between a top end and a lower end of the light emitting unit. ### Claim 13 (depends on 1) The printing apparatus according to claim 1, wherein the printing unit prints the image on the sheet by using an inkjet system. ### Claim 14 (depends on 1) The printing apparatus according to claim 1, wherein the display unit is a liquid crystal display. ### Claim 15 (depends on 1) The printing apparatus according to claim 1, wherein the display unit is an organic EL display. ### Claim 16 (depends on 1) The printing apparatus according to claim 1, wherein a predetermined surface is a surface from which the sheet on which printing is performed by the printing unit is discharged. ### Claim 17 (depends on 1) The printing apparatus according to claim 1, wherein the predetermined code is a QR code or a bar code. ### Claim 18 (depends on 1) The printing apparatus according to claim 1, wherein a side of a top end of the display unit is positioned above a side of the top end of the light emitting unit in a predetermined surface. ### Claim 19 (depends on 1) The printing apparatus according to claim 1, wherein the manual is saved in an external server. ### Claim 20 (depends on 1) The printing apparatus according to claim 1, wherein the predetermined code includes URL information being a link destination of the manual. ### Claim 21 (depends on 1) The printing apparatus according to claim 1, wherein the display unit is a display unit provided on a predetermined surface of the printing apparatus, and wherein the light emitting unit is provided on the predetermined surface and is a separate light emitting unit from the display unit.
